    Kelderman was founded in central Iowa far back in 1970 to build products for the agricultural market. In 20 years, it began to conquer the automotive market. Today the company is known as the leading manufacturer of air suspension systems, bumpers, air control systems, and truck accessories. After more than 45 years in the automotive and agricultural industries, the company keeps being family owned and following its strong commitment to creating premium products that ensure ride quality and durability in the heart of the Midwest.

    The history of Kelderman suspension systems began in 1990, when the founder and president of the company, Gary Kelderman, developed the solution for the rough riding Ram truck. That product was called the Kelderman 2-Stage Rear Air Suspension system that aimed to boost the carrying capability of the truck suspension and improve the ride. It was greatly accepted by truck owners and is still in production. The system is also available with a leveling kit that allows for running larger tires on the Ram.

    Today, Kelderman offers a wide range of additional air suspension designs for a variety of pickup trucks, RVs, chassis cab trucks, and trailers. Constantly developing new suspension solutions, the company expands its lineup with products of premium quality. Thus, it currently offers a number of Kelderman lift kits for those drivers who want to lift their vehicle without sacrificing its ride quality. From stock height systems to fully adjustable air suspension lift kits, all units are professionally designed and built with attention to the tiniest detail to guarantee reliable and lasting operation.
