Air Suspension Kits
Take the Sag Out of a Loaded Truck
Hitch up a loaded trailer or drop a slide-in camper in the bed and the back of the truck squats. Helper springs put that height back. They work alongside the factory suspension instead of replacing it, carrying part of the load so the rear sits level, the headlights point at the road and the steering stays where you left it.

Measuring your bed
Put a tape measure inside the bed, from the inside of the bulkhead (front wall) to the inside of the closed tailgate. Round to the nearest inch — a 69" measurement is a 5'8" bed.
Bed length is measured inside the box, not along the outside of the truck.

There are two ways to do it. Air helper springs are bags that mount between the frame and the axle and get inflated to match the load, with more air under a heavy tongue weight and less when the truck runs empty. Firestone Ride-Rite and Air Lift build them, and some kits pair with an onboard compressor and in-cab control while others fill at a valve.
The other way needs no air at all. Timbren and SuperSprings make progressive rubber springs that sit above the axle and engage as the suspension compresses, so there is no line to plumb and nothing to leak. They are the simpler install and stay out of the way until the truck is loaded.
Rough Country, Bilstein and Air Lift Performance round out the section, the last with coil-to-air upgrade kits aimed at ride-height adjustment rather than load support.
Common Questions
Do air bags increase how much my truck can haul?
No. Payload and gross vehicle weight ratings are set by the manufacturer, and helper springs do not change them. What they change is how the truck carries a load it is already rated for, keeping it level instead of nose-high, which helps headlight aim, braking balance and how the truck tracks in a crosswind.
Air springs or rubber springs?
Air springs adjust. You can add pressure for a heavy load and drop it back for an empty truck, and that adjustability is the reason to run one. Rubber progressive springs do not adjust, but they need no air line, no compressor and no maintenance, and they engage only as the suspension compresses. Constant load changes favor air, simplicity favors rubber.
Can you install them?
Yes, professional installation is available at every one of our 22 stores. Air kits in particular involve routing lines and mounting a valve or a compressor somewhere you can reach it and where it will not get damaged, which is the part most people would rather hand to somebody who has done it before.
