2011+ GM 2500/3500HD 4X4 6-8" REAR

Do you want to lift your 2011 or newer GM HD truck?  Kelderman has the answer.  With a Kelderman 6-8" lift kit, not only do you get the look you want from your GM HD, but you also get that incredible experience from riding on air!  A Kelderman 6-8" lift kit allows for up to 38" tires! 

By removing the rear leaf springs from your truck, Kelderman provides upper and lower bag plates, adjustable trailing arms, forward mounting side plates and industrial strength air bags to take the place of the factory suspension. A panhard bar and crossmember are also installed to help keep the rear end centered. The lift kit also provides a larger rear sway bar to help your truck tow those heavy loads without swaying from side to side. Along with an improved ride quality over traditional leaf springs, one of the best advantages of air suspension is adjustability. With our optional SLKD2WD Air Control System, your 6-8" lift can lower to a 2" lift to make it easier for you to load things in the bed of your truck or hook up to a trailer. Thanks to Kelderman, you can lower the jack on your trailer, dump the air out of the suspension and pull straight ahead without having to do as much work with your trailer. Flip another switch and the truck instantly returns to it's 6-8" ride height. See our full line-up of air controls here, including the recommended SLKD2WD Air Control System.

This 4-Link Rear Air Suspension Lift Kit is setup to run a single rear shock setup, so Kelderman carries monotube or remote reservoir Fox shocks for all lift kit applications, as well as custom Kelderman shock clamps.

"This kit is absolutely perfect for my application!  With my lift in the back, I can drop the air out to make it easier to load motorcycles.  When they are loaded, I don't have any concerns about load-carrying capacity either!

"Truck is freakin' bad ass! My wife is tripping out becuase everywhere we go people are asking to take pictures."
