Back in 1968, 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 and bolts up to the challenge, so Holzapfel called upon his many years of fastener making experience as a leading aerospace subcontractor and founded Automotive Racing Products (ARP).
In the ensuing years, ARP has grown from a backyard garage workshop into a diversified manufacturer with a combined area in excess of 200,000 square feet. These include forging, machining, finishing and packaging/warehousing facilities in Santa Paula and Ventura, California. Today, ARP’s product line contains thousands of part numbers, and has expanded to include virtually every fastener found in an engine and driveline. These range from high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR, NHRA, marine, and of course, the AMSOIL Engine Masters Challenge!
