ARP was the first company to design and engineer fasteners specifically for racing. The company was founded back in 1968 by racing enthusiast Gary Holzapfel as he saw 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 for a leading aerospace subcontractor and founded ARP.
ARP is located in Ventura, California and all processes from raw wire to finished fasteners are handled in-house, in the USA. Whether a stock item or custom fabrication, ARP has high performance fasteners covered.
