2008+ Ram 4500/5500 2-Stage Rear Air Suspension

The Kelderman 2-Stage Rear Air Suspension is an innovative design that allows you to maintain your towing capacity but significantly improve your ride quality.  Introduced in the early 1990s, the 2-Stage Rear Air Suspension has made heavy-duty truck owners across the world with a better driving experience. We recommend the 2-Stage Rear Air Suspension System for those who don’t have any issues towing with their Ram 4500 or 5500 truck but are just looking to improve the ride quality.                                                The Kelderman 2-Stage Air Suspension is designed to improve the ride of your truck, loaded or unloaded. By loosening the rear spring shackle from the frame and attaching it to the air suspension framework, you’ve effectively provided yourself with a two-stage suspension system that smoothes the road. In this system, the bumps go through the airbags before transferring onto the leaf springs. This kit is not compatible with all flatbed configurations. Please view the ‘Exploded View‘ under the Install Instructions tab to see the dimensions & spacer required for install. It is available with or without a 2.5″ hitch receiver built-in.
