About Kelderman Manufacturing
Kelderman Manufacturing operates from Oskaloosa, Iowa, where it was founded in 1970 by Gary Kelderman. The family-owned business began as a small agricultural fabrication shop serving local farmers before expanding into automotive components. The company designs and manufactures air suspension systems, lift kits, and accessories for ¾-ton and larger trucks, trailers, and RVs, alongside agricultural equipment such as the Down Corn Reel, high-volume water pumps, and biomass projects. Its 100,000-plus-square-foot facility houses laser cutters, metal benders, machining centers, and an in-house powder-coat line. Kelderman also offers third-party manufacturing and custom truck upfitting, with installation available at its headquarters. Products are distributed through more than 150 dealers across the United States, Canada, and Australia. Primary markets include the heavy-duty truck aftermarket, recreational vehicle and trailer segments, and agriculture—serving farmers and combine OEMs. The company holds drop-ship agreements with Ford and Ram, allowing dealers to send new chassis directly for upfit, and works with new-car dealerships on custom builds. Kelderman emphasizes Midwestern values and 100% American-made production. Its differentiators stem from patented innovations like the rubber track system adopted by John Deere and the original 2-Stage Rear Air Suspension developed in 1990, both still in production. Family ownership continues under President Jeff Kelderman, guiding a focus on in-house design, fabrication, and finishing.
