ARP was founded in 1968 by Gary Holzapfel as a way to help his drag racing friends not lose rounds due to fastener failures. Whether a stock item or custom fabrication, ARP has high performance fasteners covered.
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 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 and throughout the suspension and frame. These range from quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications.
Over 3000 stock part numbers covering your automotive or performance project from Head bolts to wheel studs.
