Kelderman

What Kelderman does

Kelderman Manufacturing is a privately held, family-owned American manufacturer of aftermarket air suspension systems and truck accessories, founded in 1970 and headquartered in Oskaloosa, Iowa. The company designs, engineers, and manufactures proprietary air suspension architectures for 3/4-ton and larger pickup trucks, chassis cab trucks, trailers, RVs, and motorhomes, with core technologies including the 2-Stage Rear Air Suspension (providing approximately 40-50% ride quality improvement over factory leaf springs), the 4-Link Rear Air Suspension (a complete leaf-spring replacement with trailing arms and large air springs), and modular bumper systems across the Alpha, Bravo, and Delta series. All products are manufactured at the company's 150,000+ square foot Iowa facility and sold as 100% American-made units.

The company's revenue model is built on one-time product sales across five streams: air suspension lift kits and components ($825 to over $10,030 per kit), bumpers and grille accessories ($1,100 to $2,750), agricultural products anchored by the Down Corn Reel (introduced 1977), third-party contract manufacturing services, and custom truck upfitting and installation performed at the Iowa headquarters. Distribution combines an independent dealer network of 150+ partners across the United States, Canada, and Australia with direct-to-consumer e-commerce and OEM drop-ship arrangements with Ford and Ram dealerships. The customer base spans individual heavy-duty truck owners, commercial fleet and specialty vehicle operators (RV haulers, service trucks, ambulances, recovery vehicles), RV and motorhome owners, agricultural operations, and OEMs seeking contract manufacturing capacity. There is no disclosed external investment or institutional ownership.

Direct peers

• Air Lift Company: Lansing, Michigan-based manufacturer of aftermarket air springs, air suspension kits, and on-board air compressor systems for trucks, trailers, and commercial vehicles. Direct comparable to Kelderman's air suspension and air management product lines; Air Lift's 3H electronic system is actually integrated into Kelderman installations, highlighting their tightly overlapping offerings.
• Carli Suspension: Specialty manufacturer of high-end aftermarket suspension systems for diesel heavy-duty trucks (Ford, Ram, GM). Comparable to Kelderman in targeting the premium ride-quality niche for 3/4-ton and larger trucks with engineered-to-order systems.
• Rough Country: Tennessee-based aftermarket manufacturer of lift kits, shocks, and accessories for trucks, Jeeps, and SUVs. Direct competitor to Kelderman in the consumer lift-kit category with a much broader catalog and aggressive mass-market pricing strategy.
• BDS Suspension: After-market lift kit and suspension manufacturer specializing in late-model domestic trucks and SUVs (Ford, Chevy, Ram). Competes directly with Kelderman in the heavy-duty truck suspension segment with overlapping dealer distribution channels.
• Fabtech Motorsports: California-based manufacturer of suspension lift kits and shock absorbers for trucks and SUVs. Directly comparable product portfolio to Kelderman's lift kit offerings, including aftermarket bumpers and off-road accessories.
• Icon Vehicle Dynamics: Premium aftermarket suspension manufacturer for trucks, SUVs, and off-road vehicles. Competes with Kelderman in the high-end heavy-duty truck and chassis cab suspension segment, with comparable focus on engineered-to-order systems.
• ReadyLIFT Suspension: Aftermarket suspension lift kit manufacturer focused on domestic trucks and SUVs. Directly comparable product line to Kelderman's entry-level and mid-range lift kits, serving similar price-sensitive segments of the heavy-duty truck owner base.

Broad incumbents

• Firestone Industrial Products: Air spring and air suspension specialist for commercial vehicles, RVs, and heavy-duty trucks, owned by Bridgestone. Competes with Kelderman's air suspension kits across the commercial and RV segments and offers deeper catalog breadth and OEM relationships as part of a larger industrial portfolio.
• Fox Factory: Publicly traded manufacturer of high-performance shocks, springs, and related suspension components sold under FOX, BDS, and other brands. Competes with Kelderman in premium truck and off-road suspension with much greater scale, brand depth, and capital resources.
