Description

The Kelderman 6-8" 4-Link Rear Air Suspension Lift Kit replaces factory leaf springs for improved ride quality and towing. It absorbs harsh bumps and includes: trailing arm mounts, adjustable trailing arms, airbags, upper/lower airbag mounting plates, axle clamps, rear cross member, adjustable panhard bar, and upgraded rear sway bar with end links. Shocks and air control systems are sold separately. An optional self-leveling air control system can automatically adjust height for loads, returning to 6-8" ride height, and can lower the truck to ~2" for easier trailer hookup.
