Collection: ARP Automotive Racing Products

ARP Bolts are one of the leaders in the fastening industry. They say that to be successful you must identify a need & satisfy it. Back in the early 1970s, racing enthusiast Gary Holzapfel saw that many of his friends’ broken engines were caused by fastener failure. At the time, there were no commercially available studs & bolts up to the challenge. So Holzapfel called upon his many years of fastener-making experience for a leading aerospace subcontractor & founded ARP (Automotive Racing Products). In the ensuing years, the firm has grown from what was literally a backyard garage workshop into a highly diversified manufacturer with seven operational entities in Southern California with a combined area in excess of 200,000 square feet. These include forging, heat-treating, machining, quality control finishing & packaging/warehousing facilities in Santa Paula & Ventura, California. Today, ARP’s product line contains thousands of part numbers, & has expanded to include virtually every fastener found in an engine & driveline & throughout the suspension & frame. These range from quality high-performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR & NHRA drag racing & marine applications.
