ARP

In the early 1970s, Gary Holzapfel, a racing enthusiast, founded ARP (Automotive Racing Products) after identifying the need for durable fasteners in the racing community. From a garage workshop, ARP has evolved into a diversified manufacturer in Southern California with over 200,000 square feet of operational space. Today, their extensive product line covers every engine, driveline, suspension, and frame component, serving a wide range of applications from high-performance OEM replacements to specialized hardware for elite racing series.
