Take the towing and ride quality to the next level with a Kelderman 4-Link Rear Air Suspension. If your leaf spring suspension can’t handle the heavy loads you’re putting behind your truck, then you need an upgrade to a full air suspension like our 4-Link Rear system. This kit includes upper and lower airbag mounts, adjustable trailing arms, trailing arm mounts, frame mounts, adjustable panhard bar, panhard bar mount, lower axle clams, accumulator tanks, upgraded rear sway bar assembly, air line, Schrader valves, fittings, and all necessary hardware for installation on your Silverado or Sierra. By putting those prehistoric leaf springs in the trash, you’ve given your truck a boost in towing/payload capacity, as well as improved ride quality. A full air suspension will take the harsh, jarring bounces out of your rear suspension when traveling down the road. You can pair this kit with one of our optional, self-leveling air control packages to make your truck’s rear suspension automatically adjust to the weight of your trailers. Simply back up to your trailer and hook it up to your truck, the rear suspension will squat before sensing the weight of whatever you’re towing or hauling and return back to the original ‘stock ride height’. These optional control systems will also allow you to drop the rear suspension approximately 4″ to help hook up to trailers or load items in the bed. This would be the exact same functionality you would see on a semi-tractor. Take your truck’s ride and capability from bad/average to great with the addition of a Kelderman 4-Link Rear Air Suspension.
NOTE: The installation of this kit with the optional Mechanical, Self-Leveling Air Control System may require removal of the factory spare tire.Â
