Thomas Edison had a simple formula for success: find a need and fill it, he said. Gary Holzapfel saw such a need in 1968 when he noticed that poorly made fasteners were the cause of many a racing engine failure. A veteran of making fasteners for the aerospace industry, Gary designed and built a line of top quality fasteners for engine builders and racers. That was the beginning of Automotive Racing Products (ARP). Today ARP operates from a 200,000 square feet facility in southern California. The firm builds both OEM as well as aftermarket parts, all with an emphasis on quality. ARP’s customer base includes IndyCar, NASCAR and Formula 1. Drag racing and marine enthusiasts as well have come to depend on ARP for the cutting edge products they need to ensure their safety while giving them the winning edge. ARP: the best products for the best people, every time. WARNING: Cancer and Reproductive Harm. PerformanceParts is an authorized reseller of ARP.
