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! 

Designed for comfort and easy adjustability, this electronically controlled kit allows for three different ride heights.  All the adjustability of a Kelderman Air Suspension allows you to lower your truck not only for easier entry, but to fit in the garage or hook up to a trailer.  Simply push a button to raise it up to the height you need once you are ready to hit the road!  The Kelderman 6-8" lift kit can be set to three different heights using a programmable AccuAir TouchPad interface that allows you to individually control each air spring's height.  The optional kit includes four ride height sensors that allow for automatic leveling for those times that your HD is hauling a load to ensure that your truck will always remain level.  Dual 12V VIAIR 444C compressors and dual 3-gallon tanks make sure that your truck is quickly at the height you want while an air dryer keeps the moisture out of the system.  The kit also includes a key fob remote which allows you to adjust the height of your vehicle from nearly one hundred feet away. 

These custom engineered 2011 & newer GM HD kits come complete with Roadmaster sway bars, all necessary bracketry and Firestone air springs.  Private-label Kelderman by Sway-A-Way 2" remote reservoir shocks and super cool billet shock clamps are also available options.  For more information on this and other air suspension lift kits for Ford, Dodge and GM pickups, or to locate a Kelderman dealer in your area, visit the dealer network section of our website, or call our toll free number at 800.334.6150.

"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!
