ARP Studs
ARP was established in 1968 after founder Gary Holzapfel witnessed many broken engines due to fastener failure. 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 quality high performance OEM replacement parts to exotic specialty hardware for Formula 1, IndyCar, NASCAR and NHRA drag racing and marine applications.
