More About ARP

Pit Stop USA is The Online Motorsports Superstore! ARP is the fastener of champions. They say that to be successful you must identify a need and satisfy it. Back in 1968 racing enthusiast Gary Holzapfel saw that many of his friendsa 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 for a leading aerospace subcontractor and founded ARPA (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 four operational entities in Southern California with a combined area in excess of 115,000 square feet. These include forging, machining, finishing and packaging/warehousing facilities in Santa Paula and Ventura, California. Today, ARPas product line contains of thousands of part numbers, and has expanded to include virtually every fastener found in an engine and driveline. 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. As a matter of fact, ARPas customer list reads like a awhoas whoa of motorsports around the world. In the past several years, virtually every major championship on the planet has been won with engines prepared by ARP customers. These include NASCAR Nextel Cup, NASCAR Busch Series, NASCAR Craftsman Truck Series, Champ Car, Indy Racing League, Formula 1, NHRA Top Fuel, NHRA Funny Car, NHRA Pro Stock, IHRA and many more. And so it goes. ARP works closely with many, many teams as a supplier of engine and driveline fasteners, and has clearly become recognized as athea preeminent source for serious racers.
