ARP - Head Studs, Head Bolts and Wheel Studs - Australian Distributor

ARP (Automotive Racing Products) was established in 1968 to respond to the need for performance studs, bolts, and fasteners for the racing engines of the day. ARP’s founder, Gary Holzapfel, saw how engines belonging to people he knew were breaking down due of fastener failure, and he made up his mind to provide the solution.

Holzapfel had a lot of experience making fasteners for a leading aerospace subcontractor. He started out with just a backyard garage workshop. With time, his business grew because of the quality and effectiveness of his products.

Today, ARP is an internationally recognized performance bolt and fastener manufacturer with several production facilities in Southern California that sit on over 200,000 square feet of real estate. They design and manufacture their products in-house, with facilities for forging, machining, heat-treating, and quality control.

ARP’s current line of products includes bolts and fasteners for engines, drivelines, suspension systems, and frames of many vehicles. In addition to making OEM replacement bolts and fasteners, ARP also makes purposefully designed specialty hardware for markets like IndyCar, Formula 1, NHRA drag racing, and NASCAR.
