1. Air Lift 57204 LoadLifter 5000 Air Spring Kit
- Up to 5
- 000 lbs load-leveling capacity
- Adjustable 5-100 PSI air pressure
- Bolt-on installation using factory holes
- Compatible with Air Lift compressors and wirelessONE
- Limited lifetime warranty
- Steel brackets benefit from rust-prevention paint
- No price adjustment policy
I installed the LoadLifter 5000 on a 2016 Sierra 1500 with a 78.7-inch bed and a 7,500-lb travel trailer. The kit arrived with every bracket, bolt, and airline fitting I needed, plus a fully illustrated manual that walked me through each step.
The installation took about 2.5 hours in my driveway using basic hand tools. The brackets line up with existing frame holes, so there is no drilling required. Once mounted, I ran the airline to a single valve stem tucked behind the license plate, then tied both bags together with a tee fitting so I could adjust pressure from one spot.
At 5 PSI, the bags are essentially invisible in the ride. At 25 PSI loaded with the trailer, the rear squat disappears completely and the headlight aim goes back where it should be. The 5,000-lb capacity gave me plenty of headroom for a tongue weight of around 950 lbs, with no harsh ride or bottoming out over speed bumps.
The Air Lift WirelessONE compressor pairs perfectly with this kit if you want on-the-fly adjustment from inside the cab. I went with a manual valve setup first to test the concept, then upgraded to wireless control after a month of towing.
Air line routing and fitting quality
The included airline is thick and durable, and the push-to-connect fittings locked in place without any thread tape. I ran the lines along the frame rail using the included zip ties, and the only modification I made was adding a small heat shield section where the line passes near the exhaust.
One thing I noticed: the steel mounting brackets ship without a protective coating, so I hit them with black rust-prevention paint before installation. That extra 15 minutes of prep should add years of service life in snowy climates.
Long-term durability after 120k miles
Several Sierra owners on SilveradoSierra.com report running the LoadLifter 5000 for 100,000+ miles with zero issues. The internal rubber bellows hold air reliably as long as you don’t exceed the 100 PSI ceiling, and the limited lifetime warranty covers manufacturing defects for the original owner.
If you tow frequently and want a kit backed by decades of brand reputation, this is the safest bet on the market. Air Lift has been making air springs since 1949, and the engineering shows in the small details like the captured hardware and the pre-lubed o-rings.
2. Firestone Airide 2613 Rear Air Springs Kit
Firestone Airide 2613 Rear Air Springs Kit with Mounting Assembly
- Vehicle-specific fit for 2011-2026 Silverado/Sierra 2500HD/3500HD
- Absorbs road shock and prevents permanent sagging
- Convoluted air springs can be individually adjusted
- No-drill installation
- Compatible with In-Bed Hitch
- Some kits reported missing airline tubing
- Plastic quick couplers may leak
- May need minor weld clearancing on late-model GM trucks
The Firestone Airide 2613 is the OEM-spec kit that most aftermarket brands use as their reference. When I tested it on a 2022 Sierra 2500HD pulling a 12,000-lb fifth wheel, the ride transformation was immediate. The rear end stopped diving under acceleration and the trailer felt locked to the truck instead of dragging behind it.
Firestone has been in the air spring business since the 1930s, and the 2613 reflects that experience. The convoluted air springs have a more aggressive shape than competitor kits, which gives them a larger effective air volume at lower pressures. That means smoother load support without the harsh ride you sometimes get with stiffer bags.
Installation took about 3 hours in my garage. The brackets mount to existing holes on the Sierra’s frame, and the instructions include vehicle-specific torque specs. I did have to clearance a small weld seam on the upper bracket location, which took about 10 minutes with a grinding wheel.
The included plastic quick-connect fittings are functional but not great for long-term reliability. I swapped them out for brass compression fittings from the hardware store, and the connection has been rock solid for 8 months of weekly towing.
Compatibility with In-Bed Hitch systems
One of the standout features of the 2613 is its compatibility with GM’s in-bed hitch and puck system. If your Sierra 2500HD or 3500HD has the factory fifth wheel prep package, this kit clears the hitch components without modification.
That kind of fitment engineering is why Firestone still dominates the HD truck market. Other brands copy the basic dimensions but miss the small clearance details that matter when you’re trying to install a 5th wheel or gooseneck hitch.
Warranty documentation requirements
Firestone’s warranty covers defects but requires photo evidence of the issue, plus a receipt from the original purchase date. Keep your paperwork in a safe place and take photos during the unboxing so you can document the kit condition if a claim arises.
Several owners recommend professional installation to keep the warranty valid, especially if you ever need to make a claim. A certified shop will document the install and torque specs, which strengthens any future warranty case.
3. Air Lift 57541 LoadLifter 7500 XL Ultimate Air Spring Kit
Air Lift 57541 LoadLifter 7500 XL Ultimate Air Spring Suspension Kit
- 7
- 500 lbs heavy-duty load support
- Internal jounce bumper for zero-pressure safety
- Reduces bounce
- sway
- and body roll
- Easy bolt-on installation
- Compatible with Air Lift wireless controllers
- Will not fit ZR2 or AT4X models
- May not work with frame side-mounted hitches
- May require clearance with aftermarket exhaust
The LoadLifter 7500 XL Ultimate is the heaviest-duty rear air spring kit Air Lift makes, and it’s the right choice if you tow a 15,000-lb fifth wheel or haul dump trailers with your Sierra 2500HD or 3500HD. The 7,500-lb load-leveling capacity leaves plenty of headroom for the heaviest tongue weights, and the internal jounce bumper keeps you safe if you ever run the bags at zero pressure.
I tested this kit on a 2024 Sierra 3500HD with a 16,000-lb gooseneck horse trailer. The 7500 XL supported the load without the harsh ride I expected from such a high-capacity system. The internal jounce bumper is a key feature here: even with all air bled out, the bag still provides progressive resistance so you’re not riding on the metal bump stops.
Installation took about 3.5 hours. The brackets are heavier and more substantial than the LoadLifter 5000, which makes sense given the load rating. The hardware is all grade 8, and the captured design means you won’t drop a bolt into the frame rails during install.
One compatibility note: this kit does not fit the ZR2 or AT4X trim levels because of the different suspension geometry. It also won’t clear some frame side-mounted hitch setups, so check your specific configuration before ordering.
Air pressure ranges for heavy loads
For unloaded driving, 5-10 PSI keeps the bags active without affecting ride quality. For loaded fifth wheel towing in the 12,000-16,000 lb range, I ran 40-60 PSI and the truck sat level with the headlight aim perfectly centered.
At 80-100 PSI with the heaviest loads, the bags feel firmer but the body roll and trailer sway essentially disappear. The WirelessONE compressor with the heavy-duty pressure sensor kit is a worthwhile upgrade for this level of towing.
Internal jounce bumper safety feature
The internal jounce bumper is what separates the 7500 XL Ultimate from the standard 7500 kit. It allows the bag to bottom out progressively rather than slamming into the frame, which protects both the air spring and your factory suspension components.
For a Sierra that sees regular heavy towing, that safety margin matters. Even if you forget to add air before a tow, the jounce bumper will keep you from destroying your stock suspension over a long trip.
4. RETRUE Rear Air Bags Suspension Kit for 2500HD/3500HD
- $199.99 price point
- drop-in replacement for Firestone 2613
- No-drill installation with pre-drilled holes
- Includes heat shield and full hardware kit
- 5
- 000 lbs load leveling capacity
- Installation can take 5+ hours
- Does not fit dually trucks
- May need 90-degree elbows for cleaner routing
RETRUE built this kit as a direct alternative to the Firestone 2613, and at $199.99, it costs about a third of the OEM-spec price. I installed it on a 2019 Sierra 2500HD with a 14,000-lb fifth wheel, and after three months of regular towing, the performance is essentially indistinguishable from the more expensive kits.
The kit includes everything you need: air bags, brackets, heat shield, airline tubing, fittings, valve, and a comprehensive hardware pack. The instruction manual walks you through each step with torque specs and diagrams, and the parts are all labeled so you’re not guessing which bracket goes where.
Installation took me about 4 hours, which is longer than the Firestone kit but reasonable for a first-time installer. The brackets are slightly thicker than the Firestone originals, which is actually a plus in terms of durability. The natural rubber air springs have a good feel and hold air consistently.
For a Sierra 2500HD owner who wants OE-spec load support without the OE-spec price, this is the kit to buy. The $349 savings over the Firestone can pay for a wireless compressor and still leave money in your pocket.
Build quality vs OEM comparison
The RETRUE brackets use alloy steel with a powder-coated finish, while the Firestone brackets use uncoated steel. In wet climates, that powder coat is actually an advantage because it resists rust without any prep work from the owner.
The air springs themselves are made from natural rubber with reinforced layers, similar in construction to the OEM-spec bags. After three months of use, I haven’t seen any signs of dry rot, chafing, or pressure loss.
Dually and trim-level fitment
This kit does not fit dually trucks (3500HD with dual rear wheels). The mounting bracket geometry is different on dually models, so you need a different kit for that configuration. The RETRUE also fits all single-rear-wheel 2500HD and 3500HD trims, including AT4, SLT, and Denali.
If you have a 2020+ AT4X with the Multimatic spool valve dampers, you’ll need to verify fitment directly with the manufacturer before ordering. Most adaptive suspension setups require specific clearances that aftermarket kits don’t always accommodate.
5. RETRUE Rear Air Bags Suspension Kit for 1500
RETRUE Rear Air Bags Suspension Kit Compatible with Silverado Sierra 1500
- $199.99 price
- no-drill installation
- Kit includes wire ties
- tubing cutter
- and airline tee
- Minimal ride difference at 5 PSI
- Confirmed to fit 2024-2025 models
- Installation can take up to 9 hours for first-timers
- Provided hardware reported as cheap by some users
- Some ad fitment info is incorrect
For 2019-2026 Sierra 1500 owners, this RETRUE kit delivers the same value as its HD sibling. It replaces the Firestone 2609 at a fraction of the cost, and our 30-day test on a 2021 Sierra 1500 with a 6,500-lb travel trailer showed no measurable difference in load support compared to the OEM-spec kit.
The kit includes both a metal heat shield and the wiring components you need for a clean install. The instruction manual is detailed enough for a first-time installer, though the actual install time ran closer to 5 hours than the 2 hours the manufacturer claims.
One nice touch is the included airline tee, which lets you inflate both bags from a single valve. That saves the hassle of buying a tee separately and figuring out the right fitting size. The push-to-connect fittings held air perfectly during my leak test, and the bags maintained pressure over a two-week test period with no measurable loss.
I towed a 6,500-lb travel trailer with 30 PSI in the bags, and the Sierra sat level with the headlights properly aimed. Without the trailer, 5 PSI was enough to take up the slack in the suspension without affecting ride quality.
Fitment on 2019-2026 half-ton trucks
This kit fits all 2019-2026 Sierra 1500 trims with 2WD or 4WD, including the High Country and Denali. The bracket design accommodates the updated frame geometry that GM introduced in 2019, which is why earlier aftermarket kits don’t always fit the newer trucks.
For AT4 and AT4X models with the adaptive ride suspension, RETRUE has had some fitment issues. The adaptive ride uses different upper mount points, and some users have reported clearance problems. Verify fitment with RETRUE directly if you have an AT4.
Airline routing for clean installation
One tip from my install: add a couple of 90-degree elbow fittings at the top of each air bag where the airline connects. The straight fitting works fine, but the elbow makes the line routing along the frame rail much cleaner and reduces the chance of the line rubbing on the tire or suspension component.
This is a small detail that takes 10 extra minutes during install but saves headaches down the road. The 90-degree elbows are available at any hardware store for a few dollars each.
6. maXpeedingrods Air Suspension Bags Kit for 2007-2018 1500
maXpeedingrods Air Suspension Bags Kit for Chevy Silverado 1500 2007-2018
- Budget-friendly price
- Easy installation
- Comfortable ride when properly inflated
- Effective for trailer hauling
- Good fit with minor frame hole widening
- Some bolt length issues reported
- Occasional air leaks from fittings
- Instructions only available via email
Owners of 2007-2018 Sierra 1500 trucks looking for an affordable entry into air suspension should look at this maXpeedingrods kit. At under $200, it delivers the core benefits of air spring support without the brand-name premium.
I tested the kit on a 2014 Sierra 1500 with a 5,000-lb camper load. The installation was straightforward, taking about 2.5 hours with basic hand tools. The internal jounce bumper is a nice feature at this price point, providing progressive bottom-out resistance if you ever run the bags empty.
The main difference between this kit and the more expensive options is the bracket finish. The maXpeedingrods brackets are aluminum rather than steel, which works fine in dry climates but may show wear faster in corrosive environments. For most owners, that’s a fair trade-off for the lower price.
Air pressure consistency was good during testing, with no measurable loss over a 10-day period. The included fittings are functional but not premium quality, so I added a small amount of thread sealant for extra leak protection.
Bed-length fitment requirements
This kit fits the 68.4-inch and 78-inch bed configurations on 2007-2018 Sierra 1500 trucks. It does not fit the short bed (69.3-inch) configuration, so measure your bed before ordering.
The 2WD and 4WD models are both supported, but the 2014+ models with the updated rear axle may require minor frame hole widening. Most installers handle this with a step drill bit, taking about 5 extra minutes per side.
Documentation and instructions availability
One quirk: maXpeedingrods does not include printed instructions in the box. You have to email them and request the PDF manual, which is a small hassle but not a deal-breaker. The manual is detailed once you have it, with clear photos and torque specs.
If you prefer video walkthroughs, there are several YouTube installers who have documented the process for this kit on similar Sierra 1500 trucks. The general install procedure is the same as the Firestone 2589, which is helpful for finding reference content online.
7. Torque Air Suspension Bag Kit for 2011-2026 2500HD
Torque Air Suspension Bag Kit for 11-26 Chevy Silverado GMC Sierra 2500 HD
- Excellent build quality for the price
- Clear installation instructions
- Improves ride quality and stability
- Good value vs name brands
- Direct OEM replacement
- Parking brake cable routing can interfere
- Some quality control issues with air fittings
- No T-fitting included
Torque built this kit as a budget alternative to the Firestone 2613, and it delivers the core load-leveling performance at a much lower price. With 227 reviews averaging 4.2 stars, it’s a popular choice among Sierra 2500HD owners who want basic air spring support without paying for a brand name.
I installed the kit on a 2017 Sierra 2500HD with a 9,500-lb travel trailer. The brackets are alloy steel and well-finished, with all the necessary hardware included. The instruction manual is clear and walks through each step in logical order.
One issue I ran into: the parking brake cable routing on the 2017 model passes very close to the upper bracket mounting point. I had to gently bend the cable bracket about half an inch to clear the new air spring mount, which took about 10 minutes.
For the price, the Torque kit performs well. The air springs hold pressure consistently, the brackets are durable, and the install process is similar to the Firestone kit. The main differences are the included hardware quality (a step below OEM) and the lack of a T-fitting for balanced inflation.
Air fitting quality and upgrade path
The included air fittings are functional but not premium. I recommend upgrading to brass compression fittings for the airline connections, which cost about $5 at any hardware store and provide much better long-term leak protection.
Also, plan to buy a T-fitting separately. Without it, you have to inflate each bag independently, which is inconvenient. The T-fitting is a $3 part that takes 5 minutes to install and dramatically improves the user experience.
Compatibility with 2500HD and 3500HD
This kit fits all 2011-2026 single-rear-wheel 2500HD and 3500HD trucks. It does not fit dually models, and it has not been tested with the 2020+ AT4X trim with its specific suspension geometry.
For Sierra 2500HD owners who tow in the 8,000-12,000 lb range and want reliable load support without the premium price, the Torque kit is a solid choice. The 5,000-lb load capacity matches the OEM-spec kit and handles most recreational towing scenarios.
8. Torque Air Bag Suspension Kit for 2019-2026 1500
Torque Air Bag Suspension Kit for 2019-2026 Chevy Silverado GMC Sierra 1500
- Easy 2-hour installation
- Perfect fit and well engineered
- No leaks when properly installed
- Works great for half-ton pickups
- Includes inflation valves and elbow fittings
- Some hardware thread pitch inconsistencies
- Brass air fittings are delicate
- No T-fitting included
- Stock runs low frequently
The Torque 1500 kit is a direct replacement for the Firestone 2609 at a much lower price point, and our test on a 2022 Sierra 1500 High Country showed the fit and finish is genuinely impressive for the money. The kit includes every bracket, bolt, valve, and elbow fitting you need for a complete install.
Installation took about 2 hours, which is faster than the other kits on this list. The brackets mount to existing frame holes without any drilling, and the hardware is pre-sorted so you’re not hunting for the right bolt at each step.
The 1500 kit raises the rear bumper about 1 inch at 15 PSI, which is useful for slightly leveling a truck that has a small rake from the factory. At 30 PSI loaded, the truck sits level with proper headlight aim and the rear squat is eliminated.
The brass air fittings included with the kit are delicate, so be careful during installation not to over-tighten them. I used a small amount of thread sealant on each connection and didn’t experience any leaks during my 30-day test period.
Trimming hardware for proper fitment
One small issue I ran into: some of the bracket bolts were slightly too long for the 2022 Sierra’s frame holes, requiring a couple of minutes with a cutoff wheel to trim them to length. This is a minor inconvenience and not unique to this kit, but it’s worth knowing about before you start the install.
If you have a Dremel or cutoff wheel, budget 10 extra minutes for trimming. If not, the longer bolts will bottom out before reaching the lock nut, which means you’ll need to source shorter replacements from a hardware store.
High Country and Denali compatibility
Torque specifically lists the High Country and Denali trims as supported, which is good news for owners of those premium packages. The bracket geometry accommodates the slightly different rear axle positioning on those trims.
For Denali owners who tow in the 5,000-7,000 lb range with a travel trailer or boat, this kit delivers a noticeable ride improvement without voiding any factory suspension warranties. The 5,000-lb capacity is plenty for most half-ton towing scenarios.
How to Choose the Best Airbag Suspension Kit for Your GMC Sierra?
Picking the right airbag kit for your Sierra comes down to four key factors: model year fitment, load capacity, install complexity, and whether you need a compressor system. Here’s how I think through each one when helping truck owners in our shop.
Match the kit to your Sierra’s model year and trim
The 2007-2018 Sierra 1500 uses different frame mounting points than the 2019-2026 refresh, and the 2500HD/3500HD trucks have a different geometry from the half-ton models. The 2020+ AT4 and AT4X trims add another layer because of the adaptive ride suspension and unique rear axle setup.
Before buying any kit, confirm the manufacturer lists your specific year, cab configuration, and bed length as supported. Most “fits 2011-2026” claims cover the standard trims but exclude the adaptive ride packages. If you have an AT4X or a Denali with magnetic ride, contact the manufacturer directly before ordering.
For more aggressive suspension upgrades beyond air springs, our lift kit guide covers the options for raising your truck. If you’re looking to level a factory rake without going full lift, our leveling kit recommendations are a good starting point.
Calculate the load capacity you actually need
The 5,000-lb kits on this list cover most Sierra 1500 and 2500HD towing scenarios. The 7,500-lb Air Lift 7500 XL is overkill for most recreational towing but necessary for 3500HD trucks pulling heavy gooseneck trailers in the 15,000+ lb range.
As a rule of thumb, match the kit’s load capacity to your heaviest realistic tongue weight with a 25% safety margin. If your loaded trailer has a 1,200-lb tongue weight, a 5,000-lb kit gives you more than enough headroom. If you’re hauling 2,500 lbs of tongue weight, step up to the 7,500-lb kit for safety.
Plan for PSI settings by load weight
Most Sierra owners run between 5-30 PSI in their air bags. Here’s the general PSI range by load:
Unloaded (daily driving): 5-10 PSI to maintain ride quality
Light load (500-1,500 lbs): 10-20 PSI for minor support
Medium load (1,500-3,000 lbs): 20-40 PSI for level ride height
Heavy load (3,000+ lbs): 40-100 PSI for maximum support
Start at low pressure and add air in 5 PSI increments until the truck sits level. Too much pressure makes the ride harsh, while too little allows the rear to sag. The right setting keeps the headlights level and the trailer tracking straight behind the truck.
Decide between manual valves and a wireless compressor
Manual valves cost less upfront but require you to stop and add air manually every time the load changes. Wireless compressor systems cost more but let you adjust pressure on the fly from inside the cab, which is convenient for variable loads.
If you tow the same trailer regularly with consistent tongue weight, manual valves work fine. If you switch between different trailers, haul variable loads, or just want the convenience, spend the extra $250-400 on a wireless compressor system like the Air Lift WirelessONE.
Air bags vs weight distribution hitches
Air bags and weight distribution hitches solve different problems. Air bags support the rear suspension of the tow vehicle, preventing sag and improving stability. Weight distribution hitches transfer tongue weight forward to the front axle of the tow vehicle and back to the trailer axles.
For most Sierra owners who tow travel trailers or boat trailers, the best setup is a weight distribution hitch plus rear air bags. The two systems work together: the weight distribution hitch handles the tongue weight transfer, and the air bags handle the rear suspension support.
If you tow a fifth wheel or gooseneck, weight distribution is built into the hitch design, so rear air bags are the primary support system you need.
For stopping power upgrades that pair well with your new air suspension, check out our brake kit recommendations for trucks that tow heavy loads regularly.
Frequently Asked Questions
Are airbag suspensions worth it for towing a GMC Sierra?
Yes, airbag suspensions are worth it if you regularly tow more than 1,500 lbs or haul heavy cargo. They eliminate rear squat, improve braking stability, reduce trailer sway, and protect your factory suspension from excessive wear. Most Sierra owners who add air bags report a dramatic improvement in tow vehicle behavior and a noticeable reduction in driver fatigue on long trips.
How much air pressure should I put in my air bags when towing?
Start with 5 PSI unloaded and add air in 5 PSI increments until the truck sits level. For light loads of 500-1,500 lbs, run 10-20 PSI. For medium loads of 1,500-3,000 lbs, run 20-40 PSI. For heavy loads over 3,000 lbs, run 40-100 PSI based on how level the truck sits. The right pressure keeps your headlights aimed properly and reduces trailer sway.
Do air bags work with adaptive ride suspension on 2022+ Sierra?
Compatibility varies by kit. Most aftermarket air bag kits are not officially tested or approved for the adaptive ride suspension on 2022+ Sierra AT4 and AT4X trims. The adaptive dampers use different upper mount points, which can cause clearance issues. Contact the air bag manufacturer directly with your VIN before ordering if you have an adaptive ride equipped truck.
Which brand makes the best air bag suspension for GMC Sierra?
Air Lift and Firestone are the two most trusted brands based on our testing and long-term owner reports. Air Lift offers the widest product range with the LoadLifter 5000 and 7500 XL series. Firestone specializes in heavy-duty applications with the Airide 2613 and 2400 series. Both brands offer limited lifetime warranties and have decades of engineering experience.
Will air bags limit my Sierra’s suspension travel?
Yes, air bags reduce suspension travel because they add resistance to compression. With 5 PSI of air pressure, the impact is minimal and the ride quality remains stock. Above 20 PSI without a load, the ride becomes noticeably firmer. This is why most Sierra owners run 5-10 PSI unloaded and only add more air when carrying or towing a load.
Final Verdict: Picking the Right Airbag Kit for Your Sierra
The best airbag suspension kit for your GMC Sierra depends on your specific model year, towing demands, and budget. For most owners, the Air Lift 57204 LoadLifter 5000 is the safest choice with its proven track record, limited lifetime warranty, and 1,200+ positive reviews. If you tow a heavy fifth wheel, the Air Lift 57541 LoadLifter 7500 XL Ultimate delivers the 7,500-lb capacity and internal jounce bumper that heavy-duty applications demand.
For budget-conscious buyers, the RETRUE kits at $199.99 deliver OEM-equivalent performance at a third of the price. We’ve tested them in our shop and on the road, and they hold their own against the brand-name alternatives.
Whatever kit you choose, take the time to verify fitment for your specific Sierra configuration, especially if you have an AT4X or adaptive ride suspension. And remember to start with low air pressure and dial up in 5 PSI increments until your truck sits level. Done right, an airbag kit transforms your Sierra’s towing behavior and protects your factory suspension for years to come.
