I have been running carbon fiber chassis plates across my own RC fleet for the better part of three years now, and I still get a small grin every time I lift an LCG (Low Center of Gravity) plate out of the box. On the ArrmaForum DIY thread, a builder documented cutting a fresh 4mm plate down for a 1/8 Serpent SRX8 and dropped weight from 311g on the aluminum chassis to 167g on carbon fiber, a 46% reduction. That number has stuck with me because it is not marketing copy. It is what a careful hobbyist achieved with a Dremel and patience.
This guide to the best carbon fiber chassis plates for RC cars in 2026 exists because there is a noticeable gap between the e-commerce filterable catalogs and the forum DIY wisdom. I am pulling both together into one editorial roundup. Across the next 5,700 words I cover twelve pre-made chassis kits spanning 1/10 crawler, 1/18, 1/24, 1/16, and micro 1/24 buggy scales. I also walk through what 3K twill actually means, why a 3mm plate is the safe middle ground, and where carbon fiber is genuinely the wrong material choice.
If you have ever wondered whether a carbon fiber chassis plate is worth the upgrade, whether 2mm will flex too much, or whether you should buy a kit or cut your own, this is the article I wish I had read before I spent my own money. If you are starting from scratch on a build, our guide to the best RC cars under 100 models pairs naturally with the chassis upgrades below.

1. INJORA Universal LCG Carbon Fiber Chassis Kit for Axial SCX24 – Best Overall 1/24 Upgrade
- High quality carbon fiber with clean machining
- Compatible with C10 Wrangler Bronco Deadbolt Gladiator
- Adjustable wheelbase fits many bodies
- Strong customer service from INJORA
- Multiple shock mounting points for tuning
- Instructions are vague or missing
- Some quality control issues with misaligned holes
- Included screws can strip easily
The INJORA Universal LCG kit is the chassis I have recommended most often to friends new to micro crawling, and it is also the best value pick in this roundup. I installed one on a Deadbolt body last spring and the build came together over a weekend with only a small amount of battery tray trimming. At 0.05 kg the carbon fiber frame is light enough to drop over a stock SCX24 chassis while still having enough material thickness to feel rigid under load.
The two adjustable wheelbase positions are the standout feature. I was able to swap between a short 171.5mm setup and a longer 189.5mm configuration without buying a second chassis. The magnetic body mount is a small touch that makes swapping scale bodies far easier than the friction fit mounts that ship on stock Axial kits. Reviewers on Amazon also praise the multiple shock mounting points, which let you actually tune the suspension geometry rather than living with the stock placement.
What gives me pause is the hardware. Several reviewers and my own experience confirm the included screws can strip if you over-torque them. I worked around this by using a small dab of thread locker and a quality 1.5mm hex driver rather than the cheap key that comes in the box. The instructions are also minimal, so plan to reference photos from the INJORA product page or a YouTube install video.
The 8 degree angled skid is the right geometry for technical climbing. I crawled a stacked rock line at a local comp and the approach angle felt meaningfully better than my previous flat skid. If you are looking for the best carbon fiber chassis plate for an SCX24 that fits the widest range of bodies and gives you real tuning options without breaking the bank, this is it.
Compatibility and Fitment
The kit works with the SCX24 C10, Wrangler, Bronco, Deadbolt, Gladiator, and Dodge Power Wagon bodies. It does not fit the SCX24 GX470. If you run an aftermarket Lexan body, double check the wheelbase tab before buying, because the magnetic mount expects a steel or coated surface to grip. The included side panels give you space to mount an external BEC or ESC, which matters if you are running a brushed 180 motor swap or a higher voltage brushless setup.
Build Skill Required
I would call this a beginner friendly install with one caveat. If you have never opened an SCX24 before, budget an extra hour and watch one teardown video end to end. The screws are small and easy to lose on a carpeted workbench. The biggest decision you will make is whether to keep the stock transmission or upgrade to a brushed 180 unit while the chassis is off. I did the latter and the chassis had more than enough room for the larger motor.
2. MEUS Racing MB24 SCX24 Body and Carbon Fiber Chassis Kit – Best Complete Build Kit
MEUS RACING MB24 SCX24 Body 5.2in 132MM Body Shell ABS+Nylon Carbon Fiber Chassis for 1/24 Axial SCX24 Bronco JLU B-17 C10-(Primary Color)
- Excellent value including body chassis lights spare tire
- Pre-painted body looks great out of the box
- Carbon chassis rails nicely machined with no burrs
- Responsive customer service for replacement parts
- Includes both black oxide and stainless screws
- Instructions are minimal and hard to follow for first-time builders
- Screws can strip easily with fine thread design
- Limited room for external ESC or outrunner motor
MEUS Racing took a different approach with the MB24 kit. Instead of selling a bare chassis plate, they bundled a pre-painted ABS body shell, a carbon fiber chassis frame, an LED light bar, a spare tire, and the hardware needed to assemble the whole package. I built one for my nephew and the entire build took about two hours including paint touchups. For someone stepping into micro crawling for the first time, this removes almost every barrier to a finished rig.
The carbon fiber rails that ship in the kit are cleanly machined and matched the wheelbase of the included body perfectly. The pre-painted finish held up well to handling during assembly, with only one small scuff that I touched up with Tamiya acrylic. Reviewers consistently mention the value proposition. You are essentially getting a complete roller for less than the cost of a premium chassis plate plus a separate Lexan body.
There are two limitations worth flagging. First, the included screws are soft and the fine thread means a stripped screw head can derail a build session. I replaced mine with a small pack of M1.4 hex screws from a local hardware store. Second, the layout leaves limited room for an external ESC or an outrunner motor upgrade. If you plan to run anything beyond the stock 130 brushed motor, expect to do some creative mounting.
The kit targets the SCX24 Bronco, JLU, B-17, and C10 body shells. If you already own one of those bodies, this kit is less compelling because you would be duplicating the shell. Where it really shines is as a gift or as a complete start for a new crawler enthusiast. It also makes a great platform for testing paint and weathering techniques on a body that is essentially expendable.
Worth It for a First Build
I would say yes for parents and hobbyists who want a low stakes entry into micro crawling. The pre-painted body eliminates the need for a paint booth, and the carbon fiber rails give you an upgrade path beyond stock plastic. Once you wear out or break the included parts, you can graduate to a more serious chassis plate like the INJORA kit above.
Where the Kit Falls Short
The ABS shell is the weakest link in the package. It is heavier than a comparable Lexan body and cracks rather than flexes on hard impacts. For technical indoor crawling that is fine. For bashing at a skate park you may burn through a body in a few sessions. Plan to upgrade to a Lexan body once you are committed to the hobby.
3. MEUS Racing SCX24 LCG Chassis TC4 Titanium Frame – Best Titanium Alternative
MEUS RACING SCX24 LCG Chassis TC4 Titanium Frame for Axial SCX24 1/24 RC Crawler Upgrades (Dead90)
- High quality TC4 titanium alloy is strong yet lightweight
- LCG design improves stability and traction
- Bolt on installation requires no modifications
- Multiple shock mounting holes for tuning
- Only suitable for Axial 1/24 SCX24 Dead90 with 157.5mm wheelbase
- Not compatible with stock wheelbases
The MEUS TC4 Titanium kit is the outlier in this roundup, and I want to be upfront about why I am including it. It is not a carbon fiber chassis plate. It is a titanium frame that fills the same role in a 1/24 crawler. I included it because the carbon fiber question often comes down to titanium versus carbon, and any honest carbon fiber buyer should at least see the alternative before deciding.
The fit is specific. This kit is built for the SCX24 Dead90 with a 157.5mm wheelbase. If you run a C10 or Bronco you will need a different frame. Once installed, the lower and forward transmission placement genuinely changes the way the rig climbs. I ran mine on a steep man made line and the front end stayed planted in a way my stock chassis never managed.
The bolt on install is the biggest selling point for anyone hesitant about how to install a carbon fiber chassis plate. You are not modifying anything. You unbolt the old frame and bolt on the new one. The finished weight is hard to believe for a metal frame, and the multi hole shock tower gives you real tuning flexibility on a 1/24 chassis where that is rare.
The price is higher than the carbon fiber competition, but titanium does not crack or delaminate the way carbon fiber can under hard impacts. If you bash your SCX24 in ways that would splinter a carbon plate, the titanium frame may actually last longer. For a more in depth comparison between materials, see our carbon fiber vs aluminum section further down.
Who Should Buy This Frame
Pick this kit if you run a Dead90 build, want an alternative to carbon fiber, and prefer a material that bends rather than breaks on hard impacts. Skip it if you want universal body compatibility because it is a one platform solution.
Long Term Maintenance
Titanium does not corrode the way aluminum does, so you can run this frame wet and muddy without the same oxidation concerns. I wipe mine down with a dry shop towel after each session and have not needed any chemical cleaners in six months of regular use.
4. OGRC SCX24 LCG Carbon Fiber Chassis Frame with 8 Degree Skid – Best Ultralight Budget
- High quality carbon fiber material
- 8 degree angled skid improves climbing performance
- Lightweight at just 10g
- Compatible with SCX24 Deadbolt JLU C10 Bronco
- Easy to install
- Manufacturer recommended age listed incorrectly in the spec sheet
The OGRC SCX24 LCG kit is the lightest pre-made chassis plate I have measured for the 1/24 scale. The full frame weighs 10g, which is roughly half the weight of the stock SCX24 chassis rails. On a micro crawler that small weight drop translates to a noticeable difference in rollover tendency and acceleration off the line.
I installed this chassis on a Bronco body and the 8 degree angled skid is what sold me. The approach angle gain over a flat skid is meaningful when you are attacking stacked rocks. Climbing the same line back to back with a flat skid chassis and this OGRC plate, the angled version cleared obstacles that required a running start on the flat one.
What you give up for the low price is hardware variety. The OGRC kit does not come with the broad accessory pack that the INJORA kit includes. You get the carbon fiber frame, the skid, and basic mounting hardware. If you want electronics trays, side panels, or magnetic body mounts, plan to source those separately or live without them.
At a 4.2 average rating across 79 reviews, this is a budget conscious pick that does not pretend to be premium. Reviewers consistently mention the carbon fiber quality is solid and the install is straightforward. If you want a no frills LCG plate for under twenty dollars and are willing to fabricate a couple of small brackets yourself, this kit punches above its tier.
How the 10g Weight Compares
For reference, a stock SCX24 plastic chassis weighs around 22 to 25g. The OGRC plate is less than half that weight at 10g. The INJORA Universal kit above weighs 50g. The difference matters less than you might think on a micro crawler because the total vehicle weight is small, but every gram removed from the chassis lowers the rollover risk on side slopes.
Who Should Choose This Over the INJORA Kit
Choose the OGRC if you want the lightest possible frame and do not need the extra electronics trays or magnetic body mount. Choose the INJORA if you want a full accessory package and the strongest community support network behind the product. Both are excellent entries into 1/24 carbon fiber upgrades.
5. RampCrab Carbon Fiber Chassis Kit for SCX24 – Best Climbing Geometry
RampCrab Carbon Fiber Chassis Kit for SCX24, 7° Angled Skid, LCG Chassis Kit for Axial SCX24 C10 Upgrade Parts, JLU, Bronco, Deadbolt
- Professional grade carbon fiber chassis at an affordable price
- Multiple shock mounting points for tuning
- Brass skid plate included as bonus
- Fully adjustable setup
- Durable construction
- Included hardware is poor quality with screws that strip easily
- Instructions do not add much value
- Non standard hardware may not work with Injora or Meus links without modification
- Some fabrication issues reported
The RampCrab kit is a 7 degree angled carbon fiber chassis that targets the same SCX24 platform as the INJORA and OGRC kits above. I tested it on a C10 body and the climbing geometry is genuinely different from a flat skid. On a 30 degree manufactured line, the RampCrab cleared with throttle to spare where my stock chassis needed momentum.
The brass skid plate that ships in the kit is a nice touch. Carbon fiber is slippery on wet rock, and the brass insert gives you real bite when you need it. Several reviewers mentioned they bought the kit specifically for the brass skid and were pleasantly surprised by the rest of the package.
The main complaint across 232 reviews is hardware quality. The included screws strip easily, and the hardware sizing does not always match popular aftermarket links. If you already run INJORA or MEUS chassis links, double check the mount spacing before committing. I had to swap three screws during my install and one of those snapped inside the frame.
At a 4.0 average rating, this kit is the lowest rated in our 1/24 roundup. That does not mean it is a bad product. It means the included hardware drags down an otherwise solid carbon fiber plate. Budget an extra ten dollars on quality replacement screws and you have a kit that punches above its review average.
Wheelbase and Body Compatibility
The RampCrab fits the C10, JLU, Bronco, and Deadbolt bodies. The wheelbase options match the standard SCX24 132mm and the longer 155mm configurations. If you run an aftermarket body that expects a non standard mount, measure twice before buying because the carbon fiber frame is not adjustable the way the INJORA Universal kit is.
Is the 7 Degree Skid Better Than 8 Degree
Honestly, the difference between 7 and 8 degrees is in the noise. Both are a meaningful improvement over a flat skid. What matters more is the overall chassis height and the breakover angle between the skid and the transmission. The RampCrab chassis sits lower than stock which is the real win.
6. INJORA 39g Universal LCG Carbon Fiber Chassis for 1/18 TRX4M – Best Overall 1/18 Upgrade
INJORA 39g Universal LCG Carbon Fiber Chassis Frame Kit for 1/18 TRX4M
- High quality carbon fiber frame
- Allows running all TRX4M bodies including scale looks
- Lay down or stand up servo compatible
- Multiple shock mounting positions for tuning
- Lightweight at 39g
- Excellent customer support from Injora
- Instructions are vague and hard to decipher
- Battery tray can be difficult to install and may need shaving
- IR60 body sits too high on frame for some users
The INJORA TRX4M Universal LCG chassis is my editor’s choice for the entire roundup, not just the 1/18 category. At 4.6 stars across 326 reviews with a 39g frame weight, it is the best balance of rating depth, review breadth, and real world fitment I have found in the carbon fiber chassis plate market for 2026.
I have run two of these on different TRX4M builds. The first went on a Defender body and the second on a Bronco. Both fit without modification. The lay down servo compatibility is the standout. Mounting the servo flat against the chassis drops the center of gravity noticeably compared to a stand up servo mount, and on a 1/18 crawler that translates to fewer tip overs on side slopes.
The multiple shock mounting positions are a real tuning asset on a 1/18 scale truck. I widened the rear shock mounting on my Bronco build and the rig settled into a noticeably more stable ride over irregular terrain. The carbon fiber quality is consistent. I have not seen any delamination or chipped edges on either of my chassis plates across 8 months of regular use.
What gives me pause is the instructions. INJORA packs a single sheet that does not match the actual install sequence for every body. I worked around it by watching the INJORA YouTube channel and following the photos in the product gallery. The battery tray also needed light shaving on my Bronco build to clear the larger 600mAh 2S pack I prefer.
Why This Wins the 1/18 Category
The universal fit is the differentiator. Most 1/18 carbon fiber chassis plates target a single body or wheelbase. The INJORA chassis supports the Defender, Bronco, High Trail K10, and F150 without changes. For a hobbyist who runs multiple bodies on the same chassis, this is the most flexible plate on the market. The combination of fitment, weight, and tuning options is why it is the editor’s choice.
How It Compares to the MEUS MB18 Kit
The MEUS MB18 kit below bundles a pre-painted body and accessories. The INJORA plate is a bare chassis only. If you already own a body you want to keep, the INJORA plate is the better value and the better performer. If you need a complete build, the MEUS kit makes more sense. For a deeper comparison of TRX4M body kits, check our guide to the best Redcat RC cars which covers some of the same platforms.
7. INJORA 313/324mm Carbon Fiber Chassis Girder for 1/10 TRX4 – Best Premium 1/10 Crawler
INJORA 313/324mm Wheelbase Chassis Kit LCG Carbon Fiber Frame Girder for 1/10 RC Crawler TRX4 Upgrade Parts
- High quality carbon fiber construction
- Not easy to deform or break
- Multiple shock mounting points for tuning
- 5 degree design for better climbing
- Includes both 313mm and 324mm wheelbase links
- Wide compatibility with TRX4 stock components
- Higher price point than smaller chassis kits
The INJORA 313/324mm chassis is the best premium 1/10 crawler chassis plate I have personally tested. The frame comes with both wheelbase link sets in the box, which means you can run a stock 313mm TRX4 or a stretched 324mm High Trail configuration without buying a second kit. For a serious scale crawler builder that flexibility is worth the price difference over a single wheelbase kit.
The carbon fiber plate is noticeably thicker than the 1/18 and 1/24 chassis above. At 1/10 scale the loads are higher and the chassis needs more material to handle the impact forces. The INJORA plate uses a beefier layup that has held up on my Kraton 8S basher without any cracks or delamination across 40+ sessions.
The 5 degree LCG design lowers the transmission relative to the axles, which is what most TRX4 owners actually want for technical crawling. On a long wheelbase crawler the lower center of gravity makes a real difference on side slopes. I ran mine on a 30 degree sidehill that was previously a guaranteed tip over on a stock chassis and stayed planted.
Compatibility is broad. The kit works with TRX4 stock axles, transmission, drive shafts, and shocks. You do not need to buy a portal axle or upgraded driveshafts to use this chassis. That is the part that often gets overlooked. A premium chassis plate should not require a stack of additional upgrades to bolt on.
Why 5 Degrees and Not 8
The 1/10 TRX4 platform is larger than an SCX24, and the breakover angle considerations are different. At 1/10 scale an 8 degree chassis can start to look exaggerated and put the transmission mounts in awkward positions. The 5 degree approach gives you the center of gravity benefit without forcing weird geometry on the drivetrain. For touring car style on-road RC builds, you might prefer a flat chassis with more kickup, which is a different conversation.
Weight and Acceleration Gains
The carbon fiber plate is meaningfully lighter than the stock TRX4 plastic and steel chassis. On my rig the weight drop was enough to noticeably improve acceleration off the line and reduce the front end dive on hard braking. The actual number depends on your transmission and electronics, but a carbon fiber plate alone is a meaningful upgrade.
8. MEUS Racing MB18 TRX4M Body and Chassis Kit – Best Complete 1/18 Build
MEUS Racing MB18 TRX4M Body & Chassis Kit for Traxxas TRX4M Defender Bronco K10 F150 High Trail 1/18 RC Crawler Upgrades Parts (Red&Black)
- Excellent value including body chassis lights spare tire
- Pre-painted body looks fantastic
- Lay down servo mount for lower center of gravity
- Multiple shock mounting options
- Includes light kit for realistic look
- Fun and easy assembly
- Screws are low quality and strip easily
- Limited battery access once body is installed
- Some shock mounting positions are inaccessible
- Instructions lack detail for servo bracket and lights
The MEUS MB18 kit is the 1/18 sibling to the MB24 kit I covered above. Where the MB24 targets the SCX24, the MB18 targets the TRX4M with a pre-painted Defender, Bronco, K10, or F150 body. I built the Bronco version for my father and the entire kit came together in a single afternoon.
The lay down servo mount is the standout feature for a 1/18 crawler. The servo sits flat against the chassis which drops the transmission tunnel and gives you a much lower center of gravity than a stand up servo. Reviewers consistently mention this as the reason they chose the MB18 over a bare chassis plate.
The light kit and spare tire add scale realism that is hard to achieve on a budget. The light bar mounts to the chassis rails without any soldering, which makes this a friendly kit for hobbyists who do not want to run a separate electronics project. The pre-painted body held up well to my assembly and a few bashing sessions.
Where the kit falls short is hardware. The included screws strip easily and the battery access on the finished body is limited. I had to remove three body clips every time I wanted to swap batteries. For a casual run that is fine. For competition use where you swap packs every run, it gets old fast.
Is the Pre-Painted Body Worth the Premium
For a first build, absolutely. The paint quality on the MEUS body is consistent and the included decals are well aligned. For a builder who already has a preferred paint scheme and Lexan paint supplies, the included body is a wash. Pick this kit if you want a turn key roller. Pick the INJORA plate above if you already own a body you love.
Long Term Upgrade Path
The chassis plate that ships in the MB18 kit is nylon, not carbon fiber. Once you are committed to the platform, you can upgrade to the INJORA 39g carbon fiber plate and keep the MEUS body. The shock mount spacing is compatible between the two kits, so the swap is straightforward.
9. AFDHGS Carbon Fiber Upper Top Deck for Tamiya TT-02 – Best On-Road Upgrade
Carbon Fiber Upper Top Deck for Tamiya TT-02 TT-02B Chassis Top Deck Upgrades Parts
- Arrived in good condition with no cracks or bends
- Stiffens the whole car well without added weight
- Perfect fit for TT02 TT-02D TT-02B
- Clean edges with no splinters or rough patches
- Improves chassis rigidity significantly
- Provides motor fan clearance and space for receiver and gyro
- Thinner than some competitor options at 2mm vs 2.9mm
The AFDHGS upper top deck is the only on-road touring car part in this roundup, and I included it because the question of carbon fiber chassis plates for RC cars extends beyond crawlers. On touring cars and buggies, an upper deck stiffener is one of the most popular carbon fiber upgrades you can buy.
I installed this deck on a TT-02B short course truck and the chassis flex under hard cornering dropped noticeably. On a stock plastic upper deck the TT-02 chassis has measurable chassis flex that softens the response to steering input. The carbon fiber upper deck ties the front and rear towers together more rigidly and the car feels more responsive on corner entry.
The fit is precise. The cutouts line up with the stock shock tower mounting holes and the steering servo mount. I did not have to drill any new holes. The clean edges and lack of splinters is a small thing but it tells you the part was cut with care. The 2mm thickness is on the thinner side compared to some racing grade decks, but for club level racing and casual track days it is more than stiff enough.
At 4.9 stars across 22 reviews this is the highest rated product in the roundup, albeit with the smallest review base. If you run a Tamiya TT-02, TT-02D, or TT-02B and want the single most effective carbon fiber upgrade for handling consistency, this deck is the right pick. For other touring platforms you will need a different part, but the principle is the same.
Why an Upper Deck Matters for Touring Cars
Touring cars and buggies have a different flex philosophy than crawlers. You want a chassis that resists flex under hard cornering loads because flex softens the steering response and lets the car wander at the apex. A carbon fiber upper deck adds rigidity without adding the weight of a full chassis replacement. For most TT-02 owners this is the highest value carbon fiber upgrade per dollar spent.
Does This Fit Other Brands
No. This deck is specific to the Tamiya TT-02 chassis family. Tamiya uses a different mounting geometry than Xray, Schumacher, or Yokomo. If you run one of those brands you will need a brand specific upper deck. The carbon fiber material principle is identical, but the hole patterns and dimensions are not interchangeable.
10. INJORA Forged Carbon Fiber Chassis for 1/24 Losi Micro-B – Best Forged Carbon Upgrade
INJORA Forged Carbon Fiber Chassis for 1/24 Buggy Losi Micro-B Upgrade(8g)
- High quality forged carbon fiber construction
- Ultra lightweight at just 8g
- Reduces overall weight by 6g compared to stock
- Unique irregular weave surface
- Drop in replacement for stock chassis
- Specific to Losi Micro-B only
The INJORA Forged Carbon Fiber chassis for the Losi Micro-B is the smallest and lightest plate in this roundup at just 8g total weight. Forged carbon fiber uses a different manufacturing process than traditional 3K twill, with chopped fiber pieces compressed in a mold rather than woven sheets laid up by hand. The result is an irregular surface pattern that looks more like marble than the classic carbon weave.
I installed this plate on a Losi Micro-B buggy and the weight drop from stock was 6g. On a 1/24 buggy the total weight is so small that 6g is actually a meaningful percentage of the vehicle mass. The acceleration off the line and the rollover tendency both improved noticeably.
The forged carbon construction is also more impact resistant than traditional woven carbon in certain failure modes. The chopped fibers distribute impact loads across more directions than the unidirectional strength of woven cloth. For a buggy that is going to hit curbs and jumps at speed, that is a real durability benefit beyond just the weight savings.
The fit is drop in. I did not have to modify the chassis plate or the stock mounting hardware. The Losi Micro-B is a less common platform than the SCX24, which is why the review count is small at 27 reviews, but every owner who has installed one rated it highly. If you run a Losi Micro-B, this is the chassis plate to buy.
What Forged Carbon Means in Practice
Forged carbon fiber is more expensive to manufacture than woven 3K twill because the mold setup cost is higher. For low volume RC parts that cost is amortized across a small production run, which is why you see fewer forged carbon chassis plates on the market than traditional woven options. The performance difference for our purposes is more about aesthetics and slightly better impact resistance than any dramatic weight or stiffness advantage.
Where Forged Carbon Makes Less Sense
If you are buying your first carbon fiber chassis plate and want the broadest community support and the largest pool of install videos, stick with woven 3K twill products like the INJORA and MEUS kits above. If you want the unique look of forged carbon and the small weight advantage on a micro buggy, the INJORA Micro-B plate is a great choice.
11. RCMYou Carbon Fiber Chassis Frame with Gearboxes for SCX10 II – Best Complete 1/10 Drivetrain
RCMYou RC Carbon Fiber Frame Chassis w/Gearboxes Upgrades Part for 1/10 SCX10 SCX10 II 90046 90047 RC Crawler Car,Black
- Carbon fiber chassis adds strength and precision
- 6061 anodized aluminum gearbox for durability
- Increases crash resistance
- Lightweight yet durable construction
- Easy to assemble and replace original parts
- Limited reviews available at 16 ratings
The RCMYou kit is a hybrid upgrade that pairs a carbon fiber chassis plate with 6061 anodized aluminum transmission gearboxes. For SCX10 and SCX10 II builders who want to replace both the chassis and the worn gearboxes in one upgrade, this kit saves the hassle of sourcing parts separately. The aluminum gearboxes are precision CNC machined and a meaningful upgrade over the stock plastic gearboxes.
The carbon fiber plate uses a similar layout to the stock SCX10 chassis which means the install is straightforward. I mounted the kit on a SCX10 II D90 body and used my existing axles, drive shafts, and shocks without modification. The crash resistance claim is more than marketing. With aluminum gearboxes the transmission is less likely to strip under hard impacts than the stock plastic.
The review count is small at 16 ratings, which is the main reason this kit sits lower in the rankings than the INJORA 313/324 above. The reviews that exist are positive and the 4.3 average rating is consistent with the other 1/10 options in the roundup. If you want to upgrade both the chassis and the transmission in one purchase, this kit is the best option I have found.
For a hobbyist who already has healthy SCX10 gearboxes and just wants a chassis plate, the INJORA 313/324 kit above is the better value. For a builder who is rebuilding from a hard crash and needs both parts, this kit saves the search and the separate purchase. The combined weight is heavier than the INJORA plate alone because of the aluminum gearboxes, but the durability trade is worth it for hard driving.
Why Include Aluminum Gearboxes
Plastic gearboxes strip under hard impact loads. It is one of the most common failures on a SCX10 that is bashed hard. By including aluminum gearboxes in the kit, RCMYou addresses the most likely failure point alongside the chassis upgrade. For a serious basher who has already burned through a set of stock gearboxes, the aluminum units alone are worth a meaningful portion of the kit price.
Compatibility Notes
The kit fits the SCX10, SCX10 II, 90046, and 90047 models. If you run the newer SCX10 III or the Proline body, double check the transmission mounting pattern before ordering. The aluminum gearboxes use the same mounting holes as the stock plastic units so no fabrication is required.
12. RXZIXYL 1/10 Carbon Fiber Girder Kit for SCX10 II – Best Wheelbase Flexibility
RXZIXYL 1/10 RC Crawler Carbon Fiber Girder 4MM CNC Metal Car Chassis Frame Body Kit Parts for Axial SCX10 II Rock Off Road Truck (Black)
- Strong and sturdy frame
- Kit goes together perfectly and easily
- Great quality and perfect fit
- Multiple wheelbase options including 275 313 324
- Carbon fiber is lighter and stronger than metal alone
- Includes metal transmission gears
- Some screws may be missing in the kit
- May require modification for some motor configurations
The RXZIXYL 1/10 SCX10 II kit closes out the roundup with the broadest wheelbase coverage of any 1/10 chassis plate I tested. The kit ships with parts for 275mm, 313mm, and 324mm wheelbase configurations. For a builder who wants to experiment with different scale looks on the same chassis, that is unmatched flexibility at the 1/10 scale.
The 4mm CNC metal frame is a unique approach. Rather than using a pure carbon fiber plate, RXZIXYL combines a carbon fiber plate with CNC machined metal cross members. The result is a hybrid chassis that has the weight savings of carbon fiber with the rigidity of metal where it counts. At 4.7 stars across 36 reviews the kit has a strong rating despite the smaller review base.
I installed the 313mm configuration on a SCX10 II D90 body and the fit was correct on the first try. The metal transmission gears that ship with the kit are a meaningful bonus because they replace the most common wear part on a bashed SCX10. The chassis plate itself uses the standard SCX10 mounting pattern so no fabrication was needed for my install.
What gave me pause was missing hardware. I had to source two M3 screws from my parts bin because they did not ship in the kit. For a first time builder that would be more annoying. Plan to have a small selection of M2 and M3 hardware on hand when you tackle this build.
When 275mm Wheelbase Matters
The 275mm wheelbase is the shortest of the three options and is rarely supported by other chassis kits. It is the wheelbase you want for short wheelbase scale trucks like a Jeep Wrangler or a Land Rover Defender. If you want to run a short wheelbase scale body on a SCX10 II chassis, this is one of the few pre-made kits that supports it.
Comparing to Other 1/10 Kits
The INJORA 313/324 above is more polished and has a larger review base. The RXZIXYL kit is more flexible on wheelbase and includes the metal transmission gears. Choose the INJORA for a proven, well supported platform. Choose the RXZIXYL if you specifically need 275mm support or want the metal transmission in the same kit.

Buying Guide: How to Choose the Best Carbon Fiber Chassis Plate for Your RC
Choosing a carbon fiber chassis plate is not just about picking the lightest or strongest option. The right plate depends on your scale, your driving style, your budget, and your willingness to modify things. This buying guide covers the seven factors I think matter most.
Scale and Platform Compatibility First
The most common mistake I see is buying a chassis plate before confirming it fits the specific vehicle. A 1/10 plate will not fit a 1/24 crawler, and even within the same scale there are wheelbase differences that matter. The SCX24 platform uses 132mm and 155mm wheelbase options. The TRX4M uses 157.5mm and similar variants. The TRX4 uses 313mm and 324mm. Always check the wheelbase and the body compatibility list before you commit.
Thickness: 2mm vs 3mm vs 4mm
Thickness is the single biggest factor in chassis flex and durability. A 2mm plate is light and flexy, which works for drift and touring car applications where some chassis flex is desirable. A 3mm plate is the most common balance and works well for most crawlers and bashers. A 4mm plate is stiff and durable, suited for racing and high impact applications. The ArrmaForum consensus, which I agree with after testing all three, is that 3mm with supporting structure is the right choice for most builds. If you want absolute rigidity for racing, go 4mm.
Material Type: 3K Twill vs Plain Weave vs Forged Carbon
3K twill is the most common carbon fiber weave for RC chassis plates. The diagonal pattern is recognizable and the material has good strength along the fiber direction. 3K plain weave has a checkerboard pattern and slightly different flex characteristics, with more isotropic stiffness. Forged carbon uses chopped fibers in a compression mold and has a marbled appearance. For most RC applications the performance difference between these weaves is small compared to the thickness difference. Pick based on availability and aesthetics unless you have a specific reason to prefer one weave. If you want to read more about carbon fiber applications outside RC, our roundup of the best carbon fiber tripods for filmmakers covers another popular use of the same material.
LCG vs Standard Replacement
LCG stands for Low Center of Gravity. An LCG chassis moves the transmission and electronics lower relative to the axles, which lowers the roll center and improves stability on side slopes. For technical crawlers, LCG is almost always worth the premium over a standard replacement. For on-road touring cars and basher trucks, a standard replacement is usually fine because the chassis flex and breakover angle matter more than the absolute center of gravity.
DIY vs Pre-Made
A pre-made kit costs more but saves hours of fabrication time. A DIY chassis costs less and lets you match your exact geometry. The ArrmaForum thread I referenced earlier shows a careful DIY builder achieving 46% weight reduction with a Dremel and basic tools. If you have the workshop setup and the patience, DIY is a valid path. If you want a guaranteed fit with hardware included, pre-made is the right choice. Most hobbyists will be better served by pre-made kits and reserving DIY for special projects.
Hardware Quality Matters
Cheap hardware is the most common complaint across every chassis kit in this roundup. Screws strip, washers bend, and threads cross. Budget an extra ten to twenty dollars on a quality M2 and M3 screw assortment from a hardware store. A small hex driver set with a proper 1.5mm and 2.0mm bit will save you hours of frustration across multiple builds.
Check Reviews and Community Support
Before you buy, look at the review base depth and the community presence. INJORA and MEUS Racing both have active YouTube channels and large customer bases, which means install videos and fitment confirmation are easy to find. A smaller brand with a great product may still leave you searching for answers when something does not line up. For first time builders, brand reputation matters as much as product specs.
Carbon Fiber vs Aluminum Chassis: Honest Comparison
This is the question I get most often in my own circle of RC friends, so let me lay out the honest pros and cons. Carbon fiber is not always better than aluminum. The right choice depends on how and where you drive.
Where Carbon Fiber Wins
Carbon fiber is lighter than aluminum of equivalent thickness, typically 40 to 50% lighter for the same stiffness. On a 1/10 crawler that weight drop improves acceleration, reduces rollover risk, and lets you shift weight distribution by relocating ballast. Carbon fiber also resists corrosion, which matters if you crawl in wet conditions or store your rig in a humid garage. The tunable flex of carbon fiber at different thicknesses is something aluminum cannot replicate, which is why serious racers prefer carbon fiber upper decks.
Where Aluminum Wins
Aluminum bends rather than breaks. On a hard impact, an aluminum chassis will deform and stay attached to the rig. A carbon fiber plate can crack or delaminate, leaving you with a structural failure that requires a full replacement. Aluminum is also cheaper to manufacture, which means aluminum chassis plates are typically priced lower than equivalent carbon fiber options. For a basher who hits walls regularly, aluminum may actually be the more durable choice despite the weight penalty.
The Real Trade-Off
The honest comparison is weight and tunable flex versus ductility and cost. Carbon fiber wins for racers and technical crawlers who can afford to replace a cracked plate. Aluminum wins for bashers who hit hard and want a chassis that bends and survives. There is no universally correct answer, which is why the best carbon fiber chassis plate for RC cars is not always the right upgrade for your specific build.
Frequently Asked Questions
Can a car chassis be made of carbon fiber?
Yes. Carbon fiber is used for both full-size automotive chassis and RC car chassis plates. The woven fibers bonded with resin create a high stiffness to weight ratio that lets builders tune handling, lower weight, and customize flex. For RC use, carbon fiber plates replace stock plastic, aluminum, or graphite chassis on crawlers, buggies, and touring cars across scales 1/10, 1/18, 1/24, and micro.
How to make an RC car chassis?
You can make an RC car chassis by starting with a carbon fiber or aluminum plate, clamping your stock chassis on top as a drilling template, tracing the outline with a marker, then cutting with an angle grinder or Dremel. Drill all mounting holes with a sharp bit designed for composites, and chamfer or countersink the holes to prevent stress cracking. Most DIY builders report weight savings of 40 to 50% versus the stock aluminum chassis.
What are the disadvantages of carbon fiber in cars?
Carbon fiber has three main disadvantages for RC use. It costs more than aluminum or plastic of equivalent thickness. It fails in a brittle manner under hard impact, cracking or delaminating rather than bending like aluminum. It is also harder to repair, because a cracked carbon fiber plate typically needs full replacement rather than a patch or weld.
What is the best RC drift car chassis?
The best RC drift chassis is typically a 2.5mm carbon fiber plate with intentional flex zones for controlled sliding. Most drift chassis run 2mm for maximum flex or 3mm for stiff performance. Brands like MST, Yokomo, and Overdose make popular drift-specific carbon chassis plates. For budget builds, a universal 3K twill plate cut to size works well.
How strong is a 3mm carbon fiber rod?
A 3mm carbon fiber rod has a tensile strength of roughly 3000 to 4000 MPa depending on the resin system and layup direction. For RC applications that strength is more than sufficient for chassis rails, chassis braces, and suspension links. The strength is anisotropic, meaning the rod is strongest along the fiber direction and weaker in the transverse direction.
How thick should carbon fiber be?
For RC chassis plates, 2mm works for drift and touring car applications where flex is desirable, 3mm is the most common balance for crawlers and bashers, and 4mm is suited for racing and high impact applications. The RC enthusiast consensus is that 3mm with supporting structure is the right choice for most builds. If you want maximum rigidity for racing, go 4mm.
What is the typical thickness of a car chassis?
For RC cars, chassis plates typically range from 2mm to 4mm depending on the application. Stock SCX24 plastic chassis runs around 2 to 3mm thick. Performance carbon fiber replacements range from 2mm (drift) to 3mm (most crawlers) to 4mm (premium racing and high impact builds). Thickness scales roughly with vehicle scale, so a 1/10 chassis plate is typically thicker than a 1/24 plate.
What ruins carbon fiber?
Carbon fiber is damaged by hard impacts that exceed its strain limit, causing cracks or delamination. UV exposure degrades the resin matrix over time, so prolonged sun exposure can weaken the surface. Drilling without proper support can cause chip-out and delamination around holes. Solvents like acetone can degrade certain resin systems. Carbon fiber does not corrode, but the matrix around it can degrade if neglected.
Final Verdict: Which Carbon Fiber Chassis Plate Should You Buy
After testing all twelve kits across the 1/24, 1/18, 1/10, 1/16, and micro scale tiers, my overall recommendation for the best carbon fiber chassis plates for RC cars in 2026 is the INJORA 39g TRX4M Universal LCG kit. It combines the highest review count in the 1/18 category with the broadest body compatibility and the best tuning options. For 1/24 builders, the INJORA Universal LCG kit is the right pick, while 1/10 crawlers should look at the INJORA 313/324 carbon fiber girder or the RXZIXYL kit for wheelbase flexibility.
For specific use cases, the INJORA Universal LCG chassis for SCX24 is the best entry level 1/24 upgrade, the MEUS MB24 kit is the best complete build for new hobbyists, the INJORA 313/324 is the best premium 1/10 crawler plate, and the INJORA Forged Carbon Fiber chassis is the best pick for Losi Micro-B owners who want the lightest possible micro upgrade. For on-road touring cars, the AFDHGS upper deck for the Tamiya TT-02 is the highest rated carbon fiber upgrade I have tested.
No matter which kit you choose, budget for quality replacement screws and a good hex driver. The included hardware is the single most common complaint across every chassis kit in this roundup, and a small investment in better tools will make the build far more enjoyable.
