Leaf springs wear out over time. If you have a worn-out set of leaf springs or you’re just tired of dealing with them, upgrade your truck with a 6-8″ 4-LinK Rear Air Suspension Lift Kit! If your truck is already lifted or you’re just looking to lift your truck, Kelderman has an answer for high quality, air suspension ride, as well as unmatched towing ability.
This 4-Link Rear Air Suspension allows you to be free of your rear leaf spring suspension and upgrade to a full air suspension system. Our kit will include trailing arm mounts, adjustable trailing arms, upper and lower airbag mounting plates, industrial-strength airbags, a rear crossmember, adjustable panhard bar with heim ends, upgraded rear sway bar, and sway bar end links. All shock and air management packages are sold separately.
Pick one of our optional mechanical, self-leveling air control packages to let your rear air suspension automatically adjust to weight as needed. Simply hook up to your trailer and a height control valve will add air to the airbags to return to the 6-8″ ride height. One of our air control systems can also allow you to lower the rear suspension down to a 2″ lift kit to help you load items in the truck bed or hook up to trailers. The versatility and ride comfort of an air suspension lift kit is unbeatable! It’s time to go out with the old leaf springs and in with the new 6-8″ 4-Link Rear Air Suspension from Kelderman!
