2001-2010 GM 2500/3500HD 4X4 6-8" REAR

Let's face the facts...leaf springs wear out over time. So now you have a lifted truck that you love that just isn't doing the job properly. That's where a Kelderman Air Suspension comes in to help. Take those existing leaf springs and throw them in the scrap pile for an improved ride and better towing with a full air suspension. This lift kit comes complete with upper and lower air bag mounting plates, axle clamps, adjustable trailing arms, mounting side plates, larger rear sway bar, sway bar end links, as well as a panhard bar to keep the axle centered. 

 

While enjoying ride comfort you didn't think was possible in a lifted truck, you'll also be able to increase your towing abilities. By using industrial style airbags in our suspension, the 4-Link Rear air suspension will be able to handle all your trailers with ease. With our optional self-leveling air control packages, your truck can be hooked to a trailer and will sense a change in weight and add air to the bags as needed to return to the 6-8" ride height. Many air control systems can also help with loading and unloading from the truck. At the push of a button, the 6-8" lift kit can drop to a 2" lift and then return to the proper ride height for driving down the road. This will save you a lot of time hooking and unhooking your trailers! See all of the available air control systems here, including the recommended SLKD2WD self-leveling air control system. .
