Description

Kelderman 6-8" 4-Link Rear Air Suspension Lift Kit for 2020+ GM 2500/3500 4x4 trucks. Replaces leaf spring suspension with air suspension for improved ride quality and towing. Kit includes: trailing arm mounts, adjustable trailing arms, airbags, upper and lower airbag mounting plates, axle clamps, rear cross member, adjustable panhard bar, upgraded rear sway bar, and sway bar end links. Shock and air control systems are sold separately. Optional self-leveling air control systems (like SLKD2WD) provide an onboard air compressor, tank, height control valves, and other components for automatic weight adjustment and the ability to lower the truck to approximately a 2" lift for easier trailer hookup. Air suspension lift kits are not available for the front on 2011+ GM trucks due to IFS, but Kelderman offers a 7-9" static height lift kit for the front. Perfect for up to 38" tires.
