ARP was founded in 1968 by racing enthusiast Gary Holzpfel. He identified an area of need after observing that many broken engines were caused by fastener failure. At that time there were no studs and bolts available commercially that could do the job. To meet the needs of customers, he called upon his experience in making fasteners for a leading aerospace subcontractor, and ARP was born.

Since then ARP has grown to from a backyard workshop into a highly diversified manufacturer. They facilities in Southern California, with a combined square footage of over 200,000.
