Product Details

One-ton trucks need heavy-duty suspension. Now you can have the capability of heavy-duty suspension without a heavy-duty ride quality thanks to a Kelderman 10-12″ 4-Link Rear Air Suspension. This kit removes your existing leaf springs and converts them entirely over to air ride. With the help of Industrial airbags, your Ram will now have a smooth ride quality and an increased capacity, both better than stock! This kit will provide upper and lower air bag mounting brackets, airbags, axle clamps, adjustable trailing arms, adjustable panhard bar with heim ends, larger rear sway bar, sway bar end links, and rear crossmember.

Use this with our 10-12″ Front Air Suspension Lift Kit and the optional Air Lift 3H Air Control System and you can raise & lower your truck at the push of a button. With no air in the system, the
truck will drop down to about a 5″ lift to make it easy to get in & out of your truck, park in your garage, load items in the bed, and hook up to trailers. Re-inflate the truck to the 10-12″ ‘ride height’ setting for an unbeatable ride quality while driving down the road. Want to show off what your truck can do? This kit can go up to a 17-18″ lift when fully inflated!

Designed for use with 40″ tires, this kit is THE BEST option for your suspension needs. The front lift kit and air control system are sold separately.
