2001-2010 GM 2500/3500HD 4X4 10-12" REAR

Looking to get your GM truck up in the air, but want to avoid the rough ride of leaf springs? Kelderman Air Suspension Systems provides the solution to rough riding leaf springs with a full 4-Link Rear Air Suspension System for 2001-2010 GM 2500/3500 4x4 trucks. By removing the factory leaf springs, a Kelderman 4-Link Rear Air Suspension allows your truck to ride completely on air by placing an industrial strength airbag between the axle and frame. This kit comes complete with all components necessary for installation including adjustable trailing arms, forward mounting sideplates, upper and lower air bag mounting plates, larger rear sway bar, sway bar end links, as well as a panhard bar to keep the axle centered.


Look forward to improved towing with a rear air suspension and never dread your truck squatting under weight again. All you have to do is add more air to the suspension when hooked onto a trailer and drive down the road! The suspension is even capable of adjusting on it's own when equipped with optional self-leveling air controls. When equippped with the recommended SLKD2WD Air Control System, the truck will automatically sense a change in position and inflate each bag as needed to return to the proper 'ride height'. The 10-12" 4-Link Rear Air Suspension is even capable of lowering to a 6" lift to help make it easier to load cargo or hook up to trailers.
