Stempf Automotive Industries

What Stempf Automotive Industries does

Stempf Automotive Industries is a U.S.-based auto parts manufacturer focused on alignment and suspension components for the automotive aftermarket. Its product portfolio centers on branded lines — SPC AlignPro™ alignment software tool, EZ Cams™ camber adjustment cams, the xAxis™ family of flex joints, rod end joints and receivers, Builder Series ball joints, Standard and Tandem Truck Shims, Jounce Shocks, camber/caster components, and measurement gauges — plus alignment training and education services. Customers include collision repairers and auto shops (primary), heavy-duty and commercial fleet service providers, performance automotive enthusiasts, and alignment technicians and installers, served via a horizontal segmentation approach.

The business operates a distributor-led go-to-market, with products flowing through authorized resellers with a dedicated distributor login portal and regional distribution partners covering USA/Canada/Mexico, Europe, Latin America, and Asia/Australia. Pricing is quote-based via phone and email rather than publicly listed. A secondary revenue stream comes from training and education services, including online, in-house, and field training, tech articles, installation videos, a certified installer program, and consumer alignment basics — forming a long-tenured content and installer-certification library tied to the SPC brand.

As of September 2025, Specialty Products Company (operating as a division of Niwot Corporation, headquartered at 4045 Specialty Place, Longmont, CO) acquired a controlling interest in Stempf and announced product-line consolidation under unified operations. The company is led by President John Ryshavy, is private, and reports 11–50 employees. No public revenue, funding, or AI capability disclosures are present in available sources.
