Best Air Bag Shocks For Trucks for Towing and Hauling

Best Air Bag Shocks For Trucks

A strong choice in truck air bag shocks should match your exact vehicle, provide useful load support, and include the hardware needed for installation. For many owners of heavy-duty pickups, the RETRUE Rear Air Bags Suspension Kit for Silverado Sierra 2500HD 3500HD stands out with fitment for 2011–2026 models and a stated capacity of up to 5,000 pounds. This roundup also includes kits for half-ton trucks, a universal air-spring option, a heavy-duty Air Lift kit, and Gabriel adjustable air shock absorbers.

These products are not interchangeable: some are vehicle-specific helper-spring kits, while others are shocks or replacement air springs for commercial trucks. Check the fitment notes carefully, especially for model trims and suspension configurations, before selecting a product.

The RETRUE Silverado Sierra 2500HD 3500HD kit is the best overall pick for owners of compatible heavy-duty Chevrolet or GMC pickups. It lists fitment for 2011–2026 2500HD and 3500HD models, 2WD and 4WD, and load-leveling capacity up to 5,000 pounds. The kit includes air bags, brackets, a heat shield, tubing, fittings, a valve, hardware, and an installation guide.

Confirm your exact truck configuration before ordering; the product is a suspension air-bag kit, not a replacement shock absorber.

Detailed Reviews: Best Air Bag Shocks For Trucks

RETRUE Silverado 2500HD Kit

#1 · Best Overall

1. RETRUE Silverado 2500HD Kit

  • Material: Natural Rubber,Alloy Steel
  • Material Type: Natural Rubber,Alloy Steel

Best for: Heavy-duty Silverado and Sierra haulers.

Why it ranks #1: Fits 2011–2026 Silverado and Sierra 2500HD/3500HD models in 2WD or 4WD, with up to 5,000 pounds of load-leveling capacity and installation hardware.

A stated 5,000-pound load-leveling capacity gives this RETRUE kit a clear role on Silverado and Sierra 2500HD or 3500HD trucks carrying or towing substantial loads. Its rear air springs are intended to increase spring rate, reduce shock and vibration, and support steadier vehicle behavior across listed 2WD and 4WD applications.

The kit includes air bags, brackets, a heat shield, spring mount, air-line tubing, fittings, valve, and hardware, so its listed components cover the suspension and air-line installation needs. The stated 5,000-pound leveling capacity targets loaded rear ends, while the claimed reduction in shock and vibration may help keep the truck more composed under load. Fitment is specifically listed for 2011–2026 Silverado and Sierra 2500HD/3500HD 2WD and 4WD; the broad 1500 fitment of other kits does not apply here.

Pros
  • Up to 5,000 pounds of stated load-leveling capacity
  • Listed for 2011–2026 Silverado and Sierra 2500HD/3500HD
  • Covers both 2WD and 4WD applications
  • Includes air lines, fittings, valve, heat shield, and hardware
Cons
  • Its listed fitment is limited to Silverado and Sierra 2500HD/3500HD trucks.

Skip it if you own a Silverado or Sierra 1500; the RETRUE RAS2609 kit lists 1500 fitment instead.

Choose this kit if your Silverado or Sierra 2500HD/3500HD regularly hauls or tows and you want rear air-spring load leveling. Its stated application is limited to those heavy-duty truck lines, not 1500 models.

RETRUE Ford Super Duty Kit

#2 · Best Super Duty Fit

2. RETRUE Ford Super Duty Kit

  • Material: Metal
  • Material Type: Metal

Best for: Ford Super Duty load-leveling shoppers.

Why it ranks #2: Covers specified F250, F350, and F450 models across 2017–2026; it supports up to 5,000 pounds, with spacers required for lifted applications.

Fitment across listed F-250, F-350, and F-450 2WD and 4WD configurations makes this RETRUE kit a targeted option for Ford Super Duty owners. It offers up to 5,000 pounds of stated load-leveling capacity and includes air bags, brackets, and an installation guide, with spacers required for lifted applications.

The stated 5,000-pound capacity targets rear load leveling for Super Duty trucks, while the included air bags and brackets form the main listed suspension components. Fitment covers specified 2017–2026 F-250, F-350, and F-450 configurations, including single- and dual-wheel applications. Owners of lifted trucks need spacers, a specific installation consideration that can affect parts planning. The supplied kit information lists an installation guide but does not enumerate air-line components, so buyers should review the complete contents before planning installation.

Pros
  • Up to 5,000 pounds of stated load-leveling capacity
  • Listed for F-250, F-350, and F-450 applications
  • Covers 2WD and 4WD configurations
  • Single- and dual-wheel applications are specified
Cons
  • Lifted applications require spacers.

Skip it if you own a Ford F-150; the RETRUE RAS2582 kit lists 2015–2026 F-150 applications instead.

Consider this kit for a listed F-250, F-350, or F-450 used for hauling and needing rear load leveling. Lifted trucks require spacers, so account for that application-specific hardware before installation.

RETRUE Silverado 1500 Kit

#3 · Best Older 1500 Fit

3. RETRUE Silverado 1500 Kit

  • Material: Natural Rubber, Alloy Steel
  • Material Type: Natural Rubber, Alloy Steel
  • Weight: 26.9 lb

Best for: Older Silverado and Sierra 1500 owners.

Why it ranks #3: Fits many 2007–2018 Silverado and Sierra 1500 models and lists up to 5,000 pounds of capacity, with brackets, spacers, tubing, fittings, and hardware.

A stated 5,000-pound load-leveling capacity gives this RETRUE kit a practical focus for older Silverado and Sierra 1500 trucks used for hauling. Its rear air bags are listed for 2007–2018 2WD and 4WD models, with Silverado 1500 LD coverage for 2019, and the package includes brackets, spacers, air lines, and fittings.

The listed 5,000-pound capacity aims to level the rear under load, while the kit’s air bags and suspension hardware provide a vehicle-specific installation package. Included spacers, bail clamp, heat shield, tubing, fittings, valve, and hardware address mounting and air-line needs. Fitment is limited by trim and year: 2015–2018 High Country and Denali models are excluded, and the 2019 application is Silverado 1500 Light Duty LD only. Those distinctions make the model designation as important as the year.

Pros
  • Up to 5,000 pounds of stated load-leveling capacity
  • Listed for 2007–2018 Silverado and Sierra 1500 2WD and 4WD
  • Includes spacers, bail clamp, heat shield, and air-line parts
  • 2019 Silverado 1500 LD fitment is specified
Cons
  • Excludes 2015–2018 High Country and Denali models.

Skip it if you have a 2019 standard Silverado 1500; the RETRUE RAS2609 lists 2019–2026 Silverado 1500 fitment.

This fits buyers seeking rear load leveling for a listed older Silverado or Sierra 1500, including the specified 2019 Silverado LD. Trim restrictions are important: 2015–2018 High Country and Denali models are excluded.

RETRUE Ford F150 Kit

#4 · Best F150 Fit

4. RETRUE Ford F150 Kit

  • Material: Reinforced Rubber, Alloy Steel
  • Material Type: Reinforced Rubber, Alloy Steel

Best for: Eligible Ford F-150 hauling setups.

Why it ranks #4: Targets 2015–2026 F150 trucks in 2WD or 4WD and includes bags, brackets, tubing, fittings, and hardware; several configurations are explicitly excluded.

Coverage for 2015–2026 Ford F-150 2WD and 4WD models makes this RETRUE kit a focused half-ton option, with reinforced-rubber air bags and alloy-steel hardware. The listed package includes brackets, tubing, fittings, and an installation guide, while the fitment notes call for eight inches of frame-to-tire clearance.

Rear air bags provide the suspension support, while reinforced rubber and alloy-steel construction are the listed material choices. Brackets, tubing, fittings, hardware, and an installation guide are included, giving the package specified mounting and air-line components. Fitment spans 2015–2026 F-150 2WD and 4WD models, but excludes Raptor, CCD-equipped, in-bed-hitch, certain leveling-arm, and self-leveling-headlight configurations. The eight-inch frame-to-tire clearance requirement and possible minor mounting adjustment make vehicle configuration especially important.

Pros
  • Listed for 2015–2026 F-150 2WD and 4WD
  • Reinforced-rubber air bags and alloy-steel components
  • Includes brackets, tubing, fittings, and hardware
  • Eight-inch frame-to-tire clearance requirement is specified
Cons
  • Excludes Raptor and several configurations, including CCD and in-bed-hitch models.

Skip it if you need an air-bag kit for an F-250, F-350, or F-450; the RETRUE RAS2625 lists those Super Duty models.

This suits an eligible F-150 owner seeking rear air-spring support with listed installation components. Check the eight-inch clearance requirement and exclusions for Raptor, CCD, in-bed hitch, leveling-arm, and self-leveling-headlight configurations.

RETRUE Silverado 1500 Kit

#5

5. RETRUE Silverado 1500 Kit

  • Material: Natural Rubber, Alloy Steel
  • Material Type: Natural Rubber, Alloy Steel

Best for: Recent Silverado and Sierra 1500 owners.

Why it ranks #5: Fits specified 2019–2026 Silverado and Sierra 1500 models, but excludes Duramax models and directs Silverado LD or Sierra Limited owners to another kit.

Fitment for 2019–2026 Silverado 1500 and Sierra 1500 models makes this RETRUE kit a targeted rear-air-spring option for newer half-ton trucks. Its stated load-leveling capacity reaches 5,000 pounds, helping address rear-end sag during hauling, while the included air lines, fittings, valve, and brackets support a complete listed installation package.

The kit lists Silverado 1500 and Sierra 1500 2WD and 4WD fitment, including Silverado High Country 4WD and Sierra Denali 4WD, giving owners of those trims a defined application. Air bags, brackets, a metal heat shield, tubing, fittings, valve, hardware, and an installation guide are included. The stated 5,000-pound leveling capacity is aimed at loaded-truck support; however, the listing excludes Duramax models and directs Silverado LD or Sierra Limited owners to a different kit.

Pros
  • Listed for 2019–2026 Silverado 1500 and Sierra 1500
  • Covers 2WD and 4WD applications
  • Includes metal heat shield and air-line components
  • Up to 5,000 pounds of stated load-leveling capacity
Cons
  • Not compatible with Duramax models or Silverado LD and Sierra Limited applications.

Skip it if you have a Silverado LD or Sierra Limited; the RETRUE RAS2430 kit lists those models instead.

This suits owners of listed 2019–2026 Silverado 1500 or Sierra 1500 trucks seeking rear load leveling for hauling. Check the stated exclusions carefully: Duramax models and Silverado LD or Sierra Limited are not covered.

Air Lift LoadLifter 5000

#6 · Internal Jounce Support

6. Air Lift LoadLifter 5000

  • Material: Metal, Rubber
  • Material Type: Metal, Rubber

Best for: Heavy towing with internal jounce support.

Why it ranks #6: Lists up to 5,000 pounds of load-leveling capacity and 5–100 PSI adjustment, plus internal jounce support; confirm fitment because commercial chassis and DRW models are excluded.

An internal jounce bumper helps protect the Air Lift LoadLifter 5000 Ultimate springs from damage if air pressure is lost, adding a stated safety feature to a kit rated for up to 5,000 pounds of load leveling. Adjustable 5–100 PSI support lets truck owners tailor rear spring pressure for towing and hauling demands.

The 5,000-pound load-leveling capacity is intended to counter rear sag, squat, and bottoming out when towing or hauling, while the 5–100 PSI adjustment range lets drivers tune support as loads change. Internal jounce bumpers provide a backup measure if air pressure is lost. The included pair of springs, mounting brackets, hardware, and illustrated guide form the listed installation package, but fitment excludes commercial chassis and DRW models and requires the factory jounce-bumper strike-plate location.

Pros
  • Up to 5,000 pounds of stated load-leveling capacity
  • Pressure adjustment from 5 to 100 PSI
  • Internal jounce bumpers protect springs if air pressure is lost
  • Includes mounting brackets, hardware, and illustrated instructions
Cons
  • Does not fit commercial chassis or DRW models.

Skip it if you drive a commercial chassis or DRW truck; the RETRUE RAS2613 kit lists Silverado and Sierra 2500HD/3500HD applications.

A strong match for eligible truck owners who tow or haul and want adjustable support plus internal jounce protection. Confirm the truck retains the required strike-plate location; commercial chassis and DRW models are excluded.

Gabriel HiJackers 49235

#7

7. Gabriel HiJackers 49235

  • Material: Metal
  • Material Type: Metal
  • Weight: 12 lb

Best for: Multi-vehicle adjustable shock buyers.

Why it ranks #7: This is the list’s direct air-shock option, supplied as two shocks with an accessory kit and fitment spanning multiple listed truck and SUV models.

Gabriel’s HiJackers combine adjustable air shocks with shock-absorber function, offering a different approach from a separate rear air-bag kit for towing and hauling. The listed pair includes two shocks and an accessory kit, with fitment spanning numerous trucks and SUVs, including selected Silverado, Sierra, Ram, Tahoe, and other models.

As adjustable air shock absorbers, the HiJackers combine ride-control hardware with air adjustment for vehicles carrying loads or towing, according to the supplied description. A pair of shocks and one accessory kit are included, making this a shock-replacement style purchase rather than a standalone air-bag-and-bracket kit. The lengthy fitment list covers selected years and configurations across several manufacturers, so the exact vehicle application is central to choosing it; the supplied information does not state a load-leveling capacity.

Pros
  • Adjustable air shock absorber format
  • Includes two shocks and an accessory kit
  • Listed for selected vehicles from several manufacturers
  • Description identifies towing and hauling as intended uses
Cons
  • No load-leveling capacity is stated in the supplied product details.

Skip it if you want a stated 5,000-pound air-bag capacity; the Air Lift LoadLifter 5000 Ultimate lists that capacity for eligible trucks.

Choose these if your listed vehicle needs adjustable rear shocks for towing or hauling and you prefer a shock-based product. This is not presented as a separate air-bag kit, and no capacity figure is supplied.

maXpeedingrods Double Bellow Bags

#8

8. maXpeedingrods Double Bellow Bags

  • Weight: 16.75 lb

Best for: Adjustable universal air-spring shoppers.

Why it ranks #8: The universal-style bags list up to 2,500 pounds of load-leveling capacity per bag and 5–100 PSI adjustment, but require careful application and fitting checks.

Air adjustment from 5 to 100 PSI lets these maXpeedingrods double-bellow springs adapt support to changing road conditions and loads. Each bag is rated for up to 2,500 pounds of load leveling, and the listing describes broad truck applications, including Ford, GMC, Chevrolet, and Dodge models, rather than one truck-specific kit.

The adjustable 5–100 PSI range gives owners a way to change spring support for varying load and road conditions, while the stated capacity is up to 2,500 pounds per bag. Multi-ply natural rubber and the listed double-bellow construction are the core spring details supplied. These are universal bags rather than a vehicle-specific bracket kit in the supplied information, so buyers should account for the 1/2-inch NPT elbow fitting and 6 mm tube connection; thread sealant or air-line tape is recommended to avoid leaks.

Pros
  • Air adjustable from 5 to 100 PSI
  • Up to 2,500 pounds of leveling capacity per bag
  • Multi-ply natural rubber construction
  • Broadly listed for several truck makes
Cons
  • The 1/2-inch NPT fittings require suitable air-thread sealant or tape to help prevent leaks.

Skip it if you want a truck-specific kit with listed brackets and hardware; the RETRUE RAS2613 includes those components for Silverado and Sierra HD trucks.

Consider these springs if you need pressure-adjustable bags and can work with their universal-style application and specified fittings. The supplied details do not identify a complete vehicle-specific bracket package, so installation planning matters.

ZYFONLIX 7X003 Air Spring Kit

#9

9. ZYFONLIX 7X003 Air Spring Kit

  • Weight: 26.4 lb

Best for: Chevy and GMC air-spring replacement shoppers.

Why it ranks #9: This general air spring kit describes height and stiffness adjustment but provides no specific truck fitment or load-capacity figure in the supplied product details.

A rubber air spring that inflates or exhausts to adjust suspension height and stiffness gives this ZYFONLIX kit a basic load-support and ride-comfort role for Chevy and GMC trucks. Its listing identifies the 7X003 kit and describes durable rubber, including resistance to aging from UV exposure, oxygen, and ozone.

Inflating or exhausting the air spring changes suspension height and stiffness, allowing support to be adjusted rather than relying only on a fixed spring response. ZYFONLIX describes the rubber as resistant to aging under UV, oxygen, and ozone exposure, a material claim relevant to continued outdoor vehicle use. The title identifies Chevy and GMC trucks, but the supplied fitment information does not give model years or specific truck series, so the application needs careful verification before purchase.

Pros
  • Adjustable suspension height and stiffness through inflation or exhausting air
  • Rubber construction described as resistant to aging
  • UV, oxygen, and ozone resistance is specifically stated
  • Identified as a Chevy and GMC truck kit
Cons
  • The supplied fitment details do not specify truck series or model years.

Skip it if you need a stated year-and-series application; the RETRUE RAS2609 lists 2019–2026 Silverado 1500 and Sierra 1500 fitment.

This may suit a Chevy or GMC truck owner seeking an adjustable rubber air spring, especially where the aging-resistance material claim matters. The listing’s broad truck description leaves exact series and year fitment unresolved.

MILLISEC Kenworth Air Spring

#10

10. MILLISEC Kenworth Air Spring

  • Weight: 5.9 kg

Best for: Kenworth air-spring replacement buyers.

Why it ranks #10: It is a replacement air spring for specified Kenworth-related applications, not a general pickup helper kit; the listing also names Freightliner compatibility, so verify the exact part match.

The title identifies this MILLISEC air spring for Kenworth truck models K303-19, K303-22, and K303-28, giving heavy-truck owners specific model references to check. Its high-density rubber is described as airtight and durable, while air-pressure support is intended to improve load carrying, stability, ride quality, and braking effectiveness.

High-density rubber and the stated emphasis on air tightness and durability connect directly to maintaining air-spring support in service. The product description says pressure-supported load carrying can improve stability, ride quality, and braking effectiveness, while elastic material helps absorb shock. MILLISEC says direct replacement installation usually takes two hours or less and recommends professional installation for safety and efficiency. The title lists Kenworth models, although the supplied feature text also mentions Freightliner, so confirm the application against the exact truck.

Pros
  • Title lists Kenworth K303-19, K303-22, and K303-28
  • High-density rubber construction
  • Air tightness and durability are specified
  • Direct replacement installation is described as usually taking two hours or less
Cons
  • Professional installation is highly recommended in the supplied product information.

Skip it if you need a complete rear air-bag kit with brackets and lines; the RETRUE RAS2625 kit lists those components for Ford Super Duty trucks.

This is a replacement air-spring candidate for buyers checking the Kenworth models named in the title and prioritizing high-density rubber. Professional installation is recommended, and the listing’s Freightliner reference makes exact application confirmation important.

Air bags and air shocks are different parts

Air bags and air shocks are different suspension components, so check which type your truck needs before comparing products. Most options here are air spring helper kits that work alongside the vehicle’s suspension; Gabriel HiJackers 49235 is specifically described as adjustable air shock absorbers. The maXpeedingrods listing is for universal double-bellow air springs, while MILLISEC is a replacement air spring for commercial-truck applications.

These designs do not share the same fitment or installation assumptions. A product’s load-support figure does not make it a direct replacement for a shock absorber, nor does the word “air” establish compatibility.

If you are replacing worn shocks, verify that the part is an air shock for your exact vehicle. If you want help leveling a loaded pickup, compare helper-spring kits that list your truck’s year, make, model, and configuration.

Fitment exclusions can rule out a listed kit

A kit’s compatibility notes can matter as much as its headline capacity, and several products list exclusions that could rule out an otherwise suitable pickup. The newer RETRUE Silverado 1500 kit excludes Duramax models and points Silverado LD or Sierra Limited owners to a different kit. The older Silverado/Sierra kit excludes specified High Country and Denali models.

The F150 kit excludes Raptor models and trucks with CCD, an in-bed hitch, certain leveling arms, or self-leveling headlights; it also calls for 8 inches of frame-to-tire clearance. The Super Duty kit notes that lifted applications require spacers.

Air Lift’s listing excludes commercial chassis and DRW models. Treat model year and trim as a starting point, not proof of fit. Compare the complete exclusions with your truck’s equipment and suspension setup before ordering.

How to Choose Truck Air Bag Shocks

Vehicle fitment and exclusions

Start by matching the kit to your truck’s exact year, model, drive type, and configuration. The RETRUE Silverado 2500HD/3500HD kit lists 2011–2026 2WD and 4WD fitment, while its newer Silverado 1500 kit lists 2019–2026 applications but excludes Duramax models. The F150 kit covers 2015–2026 trucks, yet excludes Raptor and several suspension or equipment configurations and requires 8 inches of frame-to-tire clearance.

The Super Duty kit includes multiple F250, F350, and F450 years, with spacers needed for lifted applications. Buyers with standard, clearly listed configurations can choose a matched kit; trucks with unusual trims, lifts, or equipment need closer verification first.

Load support and pressure adjustment

Choose a stated load-support range that suits the helper-spring job, and do not assume every capacity is expressed the same way. Several vehicle-specific RETRUE kits list up to 5,000 pounds of load-leveling capacity. Air Lift also lists up to 5,000 pounds and adjustable pressure from 5–100 PSI.

The universal maXpeedingrods bags specify up to 2,500 pounds per bag and the same 5–100 PSI adjustment range. These figures describe product capacity, not permission to exceed your truck’s rated payload or towing limits.

Buyers carrying heavier loads may prefer a matched kit with a higher stated capacity; those seeking a universal option should account for its per-bag rating and confirm application requirements.

Kit contents and part type

Check whether you need helper air springs, replacement air springs, or actual air shocks, then confirm the kit includes the parts your installation requires. The Silverado and Sierra RETRUE kits include bags, brackets, air line tubing, fittings, a valve, hardware, and an installation guide; some also list heat shields or spacers. Air Lift includes two springs, mounting brackets, hardware, and an illustrated guide.

Gabriel HiJackers are the direct air-shock choice and include two shocks and an accessory kit. Buyers who want a vehicle-specific helper system should prioritize a complete kit with listed brackets and lines.

Buyers replacing shock absorbers should focus on the Gabriel product’s precise vehicle fitment rather than choosing a spring kit by capacity alone.

Which Truck Air Bag Shocks Should You Choose?

For a compatible Silverado or Sierra 2500HD/3500HD, choose RETRUE Silverado 2500HD Kit: it lists broad heavy-duty fitment and up to 5,000 pounds of load-leveling capacity. Ford Super Duty owners can select RETRUE Ford Super Duty Kit, while compatible F150 owners should consider RETRUE Ford F150 Kit after checking its exclusions and clearance note. For older Silverado or Sierra 1500 applications, RETRUE Silverado 1500 Kit is the more clearly targeted match; newer non-Duramax 1500 owners can check the other RETRUE Silverado 1500 Kit.

Air Lift LoadLifter 5000 offers 5–100 PSI adjustment, but confirm exact fitment. If you specifically need air shock absorbers rather than helper springs, compare your vehicle against Gabriel HiJackers 49235.

Choose universal or commercial replacement bags only when their application matches your vehicle.

Frequently Asked Questions

How do air spring helper kits differ from adjustable air shocks?

Air spring helper kits add air bags to support a vehicle’s suspension and help level it under load; they are not replacement shock absorbers. Adjustable air shocks combine a shock absorber with an air chamber. The RETRUE and Air Lift products listed here are helper-spring kits, while Gabriel HiJackers are adjustable air shocks.

How much air pressure should I run in truck air bags when towing?

Use the pressure range and guidance specified for your exact kit and vehicle; there is no single pressure for every truck or load. The Air Lift LoadLifter 5000 listing specifies 5–100 PSI, but that range applies to that product, not the other kits. Confirm fitment and instructions before inflating.

Can air bags correct a truck that is overloaded?

No. Air bags can help level a properly loaded truck, but they do not increase its rated payload or towing capacity. Keep the vehicle and trailer within the applicable ratings, and check that the selected kit fits your exact configuration.

Load-leveling capacity is not permission to carry more than the truck is rated for.

What should I check before ordering an air bag kit?

Confirm the exact year, make, model, drivetrain, and other configuration details against the product’s fitment information. Also check exclusions and clearance notes. For example, the editorial guidance calls out checking those details for the Ford F-150 kit; the RETRUE heavy-duty kit lists 2011–2026 2500HD and 3500HD fitment in 2WD and 4WD.

How can I tell whether I need helper springs or replacement air shocks?

Check what the product replaces and how it is described. Helper-spring kits add air bags to support the suspension; they are not shock absorbers. If you specifically need air shock absorbers, compare your vehicle with the Gabriel HiJackers 49235 fitment listing and confirm the application matches before ordering.

Final Words

For compatible Chevrolet or GMC 2500HD/3500HD pickups, the RETRUE kit is the strongest overall match in this roundup, with listed fitment and up to 5,000 pounds of load-leveling capacity. Ford Super Duty and F-150 owners should check their corresponding RETRUE kits and exact fitment. For other trucks, match the application carefully; choose Gabriel only when you need air shocks, not helper bags.
