A strong truck air bag system adds adjustable rear load support matched to your truck, hauling demands, and preferred controls. For many towing and work-truck buyers, the Air Lift 57399 LoadLifter 5000 is a compelling starting point: it lists up to 5,000 pounds of load-leveling capacity and includes the springs, mounting hardware, and installation guide. This lineup also includes 7,500-pound Air Lift springs for heavier hauling, vehicle-specific RETRUE kits for selected Silverado and Sierra models, and onboard compressor systems for adjusting air pressure.
The main distinction is whether you need the air springs themselves, a compressor to control compatible springs, or a more complete system. Check exact vehicle fitment before choosing: several kits exclude particular chassis or configurations, and the RETRUE truck kits have stated model-year and engine restrictions.
The Air Lift 57399 LoadLifter 5000 is the best overall choice in this lineup for buyers seeking truck air springs for towing or hauling. It lists up to 5,000 pounds of load-leveling capacity, targets rear sag, squat, and bottoming out, and includes two springs, mounting brackets, installation hardware, and a fully illustrated guide. Its fitment is not universal: verify the vehicle application, especially the stated fifth-wheel and cab-and-chassis notes, before ordering.

Detailed Reviews: Best Air Bag System For Trucks

#1 · Best Overall
1. Air Lift 57399 LoadLifter 5000
- Material Type: Alloy Steel, Nylon, Rubber
- Weight: 34 lb
- Material: Alloy Steel, Nylon, Rubber
Best for: Towing and hauling support.
Why it ranks #1: Its stated 5,000-pound load-leveling capacity suits towing and hauling, and the kit includes two springs, mounting hardware, and an illustrated guide.
A stated 5,000-pound load-leveling capacity gives the Air Lift LoadLifter 5000 a clear role for trucks carrying or towing substantial loads. Its adjustable air pressure helps address rear sag, squat, and bottoming out, making this spring kit relevant to owners hauling campers, boats, or work equipment.
The two air springs provide the load-support element, while adjustable pressure lets owners tailor support to changing towing or hauling demands. The supplied mounting brackets, installation hardware, and illustrated guide support the installation workflow. Air Lift lists fitment for models without a fifth-wheel hitch and most side-mount fifth-wheel applications, as well as factory in-bed hitch systems. It does not fit cab-and-chassis applications, so body configuration is an important boundary before selecting this kit.
- Up to 5,000 pounds of load-leveling capacity
- Adjustable air pressure for changing loads
- Includes two springs, brackets, hardware, and illustrated guide
- Fits factory in-bed hitch systems
- Does not fit cab-and-chassis applications.
Skip it if you have a cab-and-chassis truck; this kit excludes that configuration, so a compatible vehicle-specific suspension kit is the better direction.
Truck and SUV owners towing campers, boats, or work equipment can use its adjustable air springs to help control rear sag under load. Verify the stated hitch and chassis fitment boundaries before choosing this kit.

#2 · Highest Capacity
2. Air Lift 57577 LoadLifter 7500 XL
- Material Type: Rubber, Steel
- Weight: 58 lb
- Material: Rubber, Steel
Best for: Higher-capacity extreme hauling.
Why it ranks #2: The 7,500-pound support rating is the lineup’s highest; its internal jounce bumper and 5–100 PSI adjustment target demanding towing and hauling.
A 7,500-pound load-support rating distinguishes the Air Lift LoadLifter 7500 XL Ultimate for demanding towing and hauling. Its air springs offer adjustment from 5 to 100 PSI, while an internal polyurethane jounce bumper helps absorb shock, combining substantial support with a cushioning feature for heavy loads.
Air Lift states that the 7500 XL springs have up to 20% more volume than LoadLifter 5000 air springs, a capacity-oriented design detail for serious hauling. Pressure adjustments from 5 to 100 PSI let owners adapt support to load conditions, and the internal polyurethane bumper adds shock absorption within the spring. The kit includes two air springs, brackets, hardware, and an illustrated guide. It fits factory in-bed hitch systems but excludes commercial chassis applications.
- Up to 7,500 pounds of load support
- Up to 20% more volume than LoadLifter 5000 springs
- Adjustable pressure from 5 to 100 PSI
- Internal polyurethane jounce bumper
- Does not fit commercial chassis applications.
Skip it if you have a commercial chassis; this kit excludes that configuration, so choose an air spring system specifically listed for your chassis.
Owners of 3/4-ton or 1-ton trucks with extreme towing or hauling demands can consider this higher-capacity air spring kit. Its factory in-bed hitch fitment and commercial-chassis exclusion are important boundaries to check.

#3 · Internal Jounce Bumper
3. Air Lift 88352 LoadLifter 5000 Ultimate
- Material Type: Metal, Rubber
- Material: Metal, Rubber
Best for: Ultimate support for factory trucks.
Why it ranks #3: This 5,000-pound kit offers 5–100 PSI adjustment and an internal jounce bumper, with a limited lifetime warranty listed.
An internal jounce bumper adds a built-in cushioning element to the Air Lift LoadLifter 5000 Ultimate, alongside load leveling rated up to 5,000 pounds. Adjustable pressure from 5 to 100 PSI lets owners tailor support for towing or hauling, while the kit targets factory trucks and some lifted setups retaining the specified strike-plate location.
The two air springs and internal jounce bumper combine adjustable load support with an additional cushion inside the spring. Air Lift specifies a 5–100 PSI adjustment range, giving owners a broad pressure span for different hauling conditions. Mounting brackets, hardware, and an illustrated installation guide are included. Fitment has clear limits: it excludes commercial chassis and DRW models, and lifted trucks need the factory jounce bumper strike-plate location retained; longer carriage bolts are not included for that setup.
- Up to 5,000 pounds of load-leveling capacity
- Adjustable pressure from 5 to 100 PSI
- Internal jounce bumper
- Includes two springs, brackets, hardware, and illustrated guide
- Does not fit commercial chassis or DRW models.
Skip it if you have a commercial chassis or DRW truck; this kit excludes both, so seek a suspension kit specified for that configuration.
Truck owners towing or hauling who want adjustable support plus an internal jounce bumper can consider this LoadLifter Ultimate kit. Check the chassis, DRW, and strike-plate requirements, especially on lifted trucks, before selecting it.

#4 · Heavy-Duty Fit
4. RETRUE RAS2613 Rear Air Bags
- Material Type: Natural Rubber,Alloy Steel
- Material: Natural Rubber,Alloy Steel
Best for: Heavy-duty HD truck leveling.
Why it ranks #4: It is specified for 2011–2026 Silverado and Sierra 2500HD and 3500HD trucks and lists up to 5,000 pounds of load-leveling capacity.
A stated 5,000-pound load-leveling capacity gives the RETRUE RAS2613 a clear hauling role on listed Silverado and Sierra 2500HD and 3500HD trucks. Its rear air bags are intended to improve stability and reduce shock and vibration, bringing adjustable air support to heavy-duty towing and load-carrying applications.
The model covers 2011–2026 Chevrolet Silverado 2500HD and 3500HD and GMC Sierra 2500HD and 3500HD, in both 2WD and 4WD. That defined application range helps owners identify whether this kit targets their truck, while the included brackets, heat shield, spring mount, air lines, fittings, valve, and hardware support the installation.

- Up to 5,000 pounds of load-leveling capacity
- Fits listed 2011–2026 Silverado and Sierra 2500HD/3500HD models
- Specified for 2WD and 4WD
- Includes heat shield, spring mount, air lines, and hardware
- An onboard compressor is not listed among the included components.
Skip it if you want a kit with an onboard compressor included; the listed package contains air bags and installation parts, not a compressor.
Owners of the listed Silverado or Sierra 2500HD and 3500HD trucks seeking rear load leveling can consider this kit for towing and hauling support. Its package includes air bags and mounting components, but no onboard compressor is listed.

5. RETRUE RAS2609 Rear Air Bags
- Material Type: Natural Rubber, Alloy Steel
- Material: Natural Rubber, Alloy Steel
Best for: Silverado and Sierra 1500 fit.
Why it ranks #5: This vehicle-specific kit fits listed 2019–2026 Silverado and Sierra 1500 applications, but excludes Duramax models and certain LD or Limited versions.
Compatibility with 2019–2026 Silverado 1500 and Sierra 1500 models makes the RETRUE RAS2609 a targeted rear air-bag choice for owners of those trucks. It is specified for both 2WD and 4WD configurations, with included brackets, heat shield, air lines, fittings, and hardware forming the core installation package.
The model-specific fitment helps narrow the choice for Silverado 1500 and Sierra 1500 owners, while the included air bags and brackets provide the rear suspension support components. Air-line tubing, fittings, a valve, and a hardware pack are supplied to connect and mount the system. The kit is identified as a replacement for the Firestone Ride-Rite 2609. Check the stated boundaries carefully: Silverado LD and Sierra Limited use another kit, and Duramax models are excluded.
- Fits listed 2019–2026 Silverado 1500 and Sierra 1500 applications
- Specified for 2WD and 4WD
- Includes brackets and a metal heat shield
- Air lines, fittings, valve, hardware, and guide included
- Not compatible with Duramax models or Silverado LD and Sierra Limited applications.
Skip it if you own a Duramax, Silverado LD, or Sierra Limited; the listing excludes those applications, while other truck-specific kits may suit your vehicle.
Owners of the listed 2019–2026 Silverado 1500 or Sierra 1500 configurations should consider this rear air-bag kit for a model-specific suspension upgrade. Its stated fitment excludes Duramax models and directs LD or Limited owners to a different kit.

#6 · Complete Air System
6. Vixen Air VXX1209FW/4852DBF
- Material Type: Alloy Steel
- Weight: 98 lb
- Material: Alloy Steel
Best for: High-demand onboard air setup.
Why it ranks #6: Its universal system bundles four air springs, two 200 PSI compressors, a 5-gallon tank, valves, and a dual-gauge control panel.
Two 200 PSI compressors feed a 5-gallon tank, giving this Vixen Air system greater onboard air capacity for suspension support and other air-powered uses. Its four 2600-style air springs and four-way switch panel make it a broad package for truck owners who want load leveling alongside air access for towing or train horns.
The dual compressors increase tank air intake for faster refills, while the nine-port steel tank gives the system multiple connection points for its included components and other pneumatic needs. Four air springs and high-flow electric valves provide the suspension-control hardware, and the dual gauge panel with four-way switching puts adjustment at a central control. Water traps and remote-filter kits are also included. At 98 pounds, this is a substantial system to plan around during installation.
- Two 200 PSI compressors and a 5-gallon tank
- Four 2600-style air springs included
- Dual gauge panel with four-way switch control
- Water traps and remote-filter kits included
- The complete system weighs 98 pounds, a substantial installation load.
Skip it if you need a lighter, spring-only kit rather than a 98-pound package with compressors, tank, valves, and controls.
Truck owners seeking an all-in-one air suspension and onboard air package can use its dual compressors, tank, springs, and controls for varied demands. Account for the 98-pound system and its installation footprint before choosing it.

Why it ranks #7: This in-cab gauge-controlled compressor kit includes air hoses and hardware, but the supplied details do not state vehicle fitment or load capacity.
An in-cab air gauge control panel lets this DUBANGLONG system operate air-suspension inflation and deflation from the vehicle, keeping pressure adjustment at the driver’s reach. Its upgraded compressor combines a pure copper coil with anti-vibration pads, pairing stable operation with measures intended to reduce operating noise.
Self-locking quick-connect fittings hold air lines firmly and are described as leak-proof, helping keep connections secure during use. The baked-enamel compressor housing is specified for longer life, while anti-vibration pads support quieter, smoother operation. The kit includes an air gauge controller, hardware, and air hoses, so it centers on compressor-based suspension control. The listing gives no vehicle-specific application range, so this information alone does not establish fitment for a particular truck.
- In-cab gauge panel controls inflation and deflation
- Pure copper coil compressor
- Anti-vibration pads for quieter operation
- Self-locking quick-connect fittings and air hoses
- The listed included components do not include air springs.
Skip it if you need a complete spring-and-compressor package; the listed components center on the controller and compressor system rather than air springs.
Truck owners who already have air springs and want in-cab pressure control can consider this compressor kit for inflation and deflation. It is a control-system choice, not a listed package of air springs, so account for that boundary.

8. Air Lift WirelessONE EZ Mount
- Material Type: Alloy Steel
- Weight: 0.27 g
- Material: Alloy Steel
Best for: Wireless spring-pressure adjustment.
Why it ranks #8: Its 12-volt compressor and wireless handheld controller or mobile app adjust compatible springs, but it is an onboard compressor system, not a spring kit.
Wireless control from inside or outside the vehicle is the key convenience of Air Lift’s WirelessONE EZ Mount system. A handheld controller or mobile app lets owners inflate or deflate air springs without reaching a fixed control, while the single-path arrangement adjusts both springs equally for balanced support.
The 12-volt compressor is rated up to 120 PSI, providing onboard air for pressure changes during hauling and towing. Because the single-path system inflates and deflates both air springs together, it offers a straightforward way to maintain even pressure rather than separate side-to-side adjustment. Air Lift packages the compressor and manifold in an EZ Mount unit with controller and wiring, which simplifies component installation compared with assembling those pieces individually.
- Wireless handheld controller and mobile app
- Adjusts pressure from inside or outside the vehicle
- Single-path control changes both springs equally
- 12-volt compressor rated up to 120 PSI
- Single-path operation does not provide independent left-to-right spring adjustment.
Skip it if you need to set different pressures on each side; this single-path system adjusts both springs equally, unlike independently controlled setups.
Choose this system if you already have air springs and want wireless pressure adjustment for towing or hauling. Its equal-pressure single path suits balanced loads, but not buyers seeking separate control of each spring.

View on AmazonWhy it ranks #9: It offers in-cab and wireless controls plus a low-pressure sensor, but it supplies a compressor and control panel rather than air springs.
A low-pressure sensor that monitors airbag pressure in real time sets this RETRUE onboard compressor apart for owners who want pressure-responsive support. When pressure falls below a preset value, the system automatically inflates the airbag, while in-cab and wireless controls offer two ways to adjust or monitor pressure.
The sensor-triggered inflation can help maintain the selected pressure without requiring the driver to initiate every correction. For deliberate adjustments, the in-cab control keeps operation within reach, and wireless control lets owners observe and change pressure from outside the vehicle. This 12-volt package includes a compressor and control panel. Since no air springs are listed among its included components, it is best considered as an onboard control and compressor system for an existing airbag setup.
- Low-pressure sensor monitors airbag pressure in real time
- Automatically inflates below a preset pressure
- In-cab and wireless control options
- 12-volt compressor and control panel included
- Air springs are not listed among the included components.
Skip it if you need air springs included with the compressor; this package lists a compressor and control panel, not the bags themselves.
Owners with an existing airbag suspension who want automatic low-pressure response and both in-cab and wireless control are the intended match. Treat it as a compressor-control system, since air springs are not listed in the package.

View on AmazonAvoiding fitment and installation surprises
The biggest compatibility trap is assuming that a truck’s make and model alone guarantees fit. Air Lift 57399 excludes cab-and-chassis applications and has specific fifth-wheel notes, while Air Lift 88352 excludes commercial chassis and dual-rear-wheel models and requires the factory jounce-bumper strike-plate location. The RETRUE RAS2609 is listed for Silverado and Sierra 1500 applications but excludes Duramax models; its details also flag Silverado LD and Sierra Limited as requiring another kit.
These restrictions can outweigh a higher load rating if the brackets do not match your truck. Before ordering, match the exact model year, drivetrain, trim, chassis, hitch arrangement, and engine against the manufacturer’s current application information.
Also distinguish a spring kit, which includes bags and mounting hardware, from a compressor product, which may only adjust compatible springs.
Air springs and compressors solve different problems
An onboard compressor adds convenient pressure adjustment, but it is not automatically a replacement for an air spring kit. Air Lift 57399 and the RETRUE rear-bag kits include air springs and mounting components; Air Lift WirelessONE EZ Mount instead lists a compressor, controller, wiring, and mount. RETRUE RACS001 lists a compressor and control panel, while the Vixen system combines four springs with two compressors, a tank, valves, and controls.
This distinction matters if you already have compatible bags or are assembling a complete system. Wireless or in-cab control can make adjustments easier, but a control package still needs to match the spring setup.
The Vixen system’s two 200 PSI compressors and 5-gallon tank also represent a much larger, more involved package than a standalone pressure-control compressor; choose that complexity only if its included components suit your intended setup.
How to Choose Truck Air Bag Springs
Load-leveling capacity
Look for a listed capacity that fits your hauling demands, while treating it as the product’s load-leveling rating rather than permission to exceed vehicle limits. Air Lift 57399, Air Lift 88352, and both RETRUE rear-bag kits list up to 5,000 pounds; Air Lift 57577 lists up to 7,500 pounds. The 7500 XL is the higher-capacity choice among these products for buyers with demanding towing or hauling needs, while a 5,000-pound kit may suit buyers whose application matches that rating.
The supplied data does not establish a safe payload for any particular truck, so check the vehicle’s limits and the kit’s fitment separately.
Exact vehicle fitment
Choose by exact vehicle application, not by brand name or a broad truck category. RETRUE RAS2609 lists Silverado and Sierra 1500 fitment from 2019–2026 but excludes Duramax models and notes that certain LD and Limited models use another kit. RETRUE RAS2613 lists Silverado and Sierra 2500HD and 3500HD applications from 2011–2026.
Air Lift 57399 and 88352 also specify chassis or configuration exclusions. Buyers with one of the named RETRUE trucks may benefit from that more specific application information; owners of other trucks should confirm compatibility with the manufacturer rather than assume a universal fit.
The Vixen kit is described as universal, but its supplied information does not provide a vehicle-by-vehicle fitment list.
Spring kit or onboard air control
Decide whether you need air springs, pressure controls, or both before selecting a product. Air Lift 57399 and 88352 include two springs, brackets, and installation hardware; the WirelessONE EZ Mount lists a 12-volt compressor and wireless controller instead. RETRUE RACS001 provides a compressor and control panel, while the Vixen package includes four springs, two 200 PSI compressors, a 5-gallon tank, and control hardware.
Buyers starting from scratch may prefer a spring kit with its listed mounting parts, subject to fitment. Drivers who already have compatible springs and want easier adjustments may favor a control system.
Those seeking a bundled setup can consider Vixen, but should verify installation requirements and compatibility for their vehicle.
Which Truck Air Bag System Should You Choose?
For a broadly useful towing and hauling spring kit, choose the Air Lift 57399 LoadLifter 5000, provided its fitment notes match your truck. For the highest stated load-leveling capacity, consider the Air Lift 57577 LoadLifter 7500 XL, which lists up to 7,500 pounds; verify its factory in-bed hitch and chassis restrictions. If you own a listed Silverado or Sierra 2500HD or 3500HD, the RETRUE RAS2613 Rear Air Bags are a vehicle-specific option, while the RETRUE RAS2609 Rear Air Bags target selected 1500 models with stated exclusions.
Choose the Air Lift WirelessONE EZ Mount or RETRUE RACS001 Onboard Compressor if you already have compatible springs and need controls. For a bundled universal-style setup, the Vixen Air VXX1209FW/4852DBF includes springs, compressors, tank, and controls.

Frequently Asked Questions
How do I confirm an air bag kit fits my truck’s exact year, trim, and chassis?
Check the kit’s fitment information against your truck’s exact year, trim, cab, and chassis before ordering. Review any stated exclusions, including fifth-wheel hitch or cab-and-chassis restrictions, and contact the manufacturer if an application is unclear. Do not assume a kit fits because the truck’s make and model appear in its title.
Do I need an onboard compressor, or can I inflate the air springs manually?
You can inflate air springs manually only if the kit supports that setup and you can access its air lines and valves. An onboard compressor adds a way to adjust pressure from the vehicle, but it must be compatible with the springs. Check the kit contents and instructions before choosing between manual inflation and onboard controls.
What air pressure should I use when towing or hauling?
Use the pressure guidance provided for your specific air spring kit and adjust it for the load as instructed. There is no single pressure that applies to every truck, spring kit, and load. Check the manufacturer’s manual for operating limits, and do not exceed them; seek manufacturer guidance if the instructions are unclear.
Can I add an onboard compressor to air springs I already own?
Possibly, but confirm that the compressor system is compatible with your existing springs, lines, and controls before buying. The Air Lift WirelessONE EZ Mount and RETRUE RACS001 are compressor options for buyers who already have compatible springs. Check each system’s installation and fitment requirements rather than assuming it works with every air spring kit.
What should I check before choosing a bundled air suspension system?
Compare the listed components with what you need, including springs, compressor, tank, controls, brackets, and installation hardware. Contents vary by kit. The Vixen Air VXX1209FW/4852DBF is listed with springs, compressors, a tank, and controls; verify its application and included parts in the product information before ordering.
Final Words
For a broadly useful towing or hauling setup, the Air Lift 57399 LoadLifter 5000 is the lineup’s best overall choice, provided its fitment notes match your truck. Consider the 57577 if its higher stated load-leveling capacity suits your needs, while checking its restrictions. Match vehicle-specific RETRUE kits carefully, and choose compressor controls only when compatible springs are already in place.
Confirm application and pressure guidance before installation.
