Product Description

We hear it all the time, "I love my truck, but I hate the ride." That is probably the exact way you feel about your Ford Chassis Cab if you were searching for air suspension and ended up here. The Kelderman 2-Stage Rear Air Suspension design have been around for over 25 years and it's still available for brand new Ford, Ram, and GM trucks. Do you want to know why? Leaf spring suspension STILL rides poorly. Designed for everyone we talked to that didn't have issues towing with their truck, but just couldn't stand to ride in it anymore. Our 2-Stage Rear Air Suspension is a unique design that removes the rear leaf spring hanger/mount and attaches it to a 'floating' air suspension framework. This allows you to retain the leaf spring suspension for towing, but allows you to ride on air suspension instead of those rigid leaf springs. Our air suspension does 'float' the stock suspension to provide 3-4" of additional suspension travel for your truck. Our air suspension framework typically needs to share the same space as your existing receiver hitch,
so sometimes your hitch setup needs to be eliminated. Don't worry...we can build you a strong Class V receiver hitch to put in as a replacement to allow for the air suspension framework to bolt right up. You will still be able to use your truck as truck, but without bouncing around inside the cab. Wondering if your kit will work in conjunction with your hauler body, flatbed, etc.? Give us a call at 1-800-334-6150 or email info@kelderman.com and we can help you determine the proper kit! Here is how it works: While driving down the road, our air suspension acts as the first line of defense. The air bags absorb the harshness of the road before transferring them onto the leaf spring suspension. This is typically responsible for a 40-50% improvement in ride quality. And THAT is why we have been building it for over 25 years. If you want to take your ride quality to where it needs to be and to where it SHOULD be then the Kelderman 2-Stage Rear Air Suspension System is finally the end of your search.
