    About Us

    Nearing 50 years in business, Kelderman Air Suspensions have been known for their reliability, longevity and quality of manufacture, not to mention customer service.  The 2 stage rear air ride was developed in 1990, and in the last 5 years have been marketing this product to the bus and RV market.  Acceptance has been growing rapidly, with end users understanding that not only does this system provide a very comfortable ride for the passengers, but also helps to lower maintenance costs due to the fact that everything attached to the body also enjoys the benefit of a soft ride, thus reducing the continual jarring effect our roads and conditions lay in front of us in the everyday use of these vehicles.

    Our product is a bit over-engineered but the quality shines through time and again.  With a 3 year, 100,000 mile warranty, this system is built to withstand the everyday riggers they are put through.  Simple in design, but the most reliable in the industry, we welcome you to try our air ride to see for yourself the smoothest ride available.  Make a great bus better with the Kelderman 2 stage air ride.

    We offer kits for those OEM’s that do not offer air on certain models.  So this includes the Ford E 350/450 and F 350/450/550/650 and 750 series, Chevy HD and cutaway 3500/4500, Dodge 3500, 4500, 5500, International Terra Star, Sprinter 3500 dual wheel, Ford Transit 350HD/XL dual wheel and general medium duty trucks.  Many other models apply, but these are the most recognized in the industry.

    Competitively priced, great warranty, virtually maintenance free and superior customer service, make Kelderman the choice for your fleet.
