Take ride quality and towing capacity to the next level with a Kelderman 4-Link Rear Air Suspension System. Not only does this suspension eliminate your factory leaf spring suspension, but it also raises your truck’s ‘ride height’ to match up with our 3″ Front Air Suspension Lift Kit. Designed to comfortably run 35″ tires, this 4-Link Rear Air Suspension provides the comfort & capability you expect from Kelderman, along with a better appearance. Our 4-Link Rear Air Suspension kit includes upper and lower airbag mounting plates, axle clamps, adjustable trailing arms, trailing arm mounts, panhard bar mount, adjustable panhard bar, oversized rear sway bar, and sway bar end links. This 4-Link Rear Air Suspension is designed for Ram 3500 trucks equipped with the newer style, radius arm front suspension from the factory. Kits are also available for Ram 3500 trucks equipped with the factory supplemental air suspension design. Choose from one of our optional self-leveling air control systems to supply your truck with onboard air and the capability for your suspension to automatically adjust to weight as needed. When used with our 3″ Front Air Suspension Lift Kit and the Air Lift 3H Electronic Air Control System, your Ram 3500 will be able to deflate below ‘stock height’ to allow for an easier entry/exit of the truck. You can also deflate the rear suspension to help you load items into the bed or to attach your trailers.
