Description

Whether it's for a full rebuild or standard maintenance, proper engine components are needed to ensure your vehicle is running smoothly. ARP (Automotive Racing Products) was founded in the early 1970s by Gary Holzapfel, who saw a need for stronger fasteners in racing engines due to common fastener failure. The company has since grown into a highly diversified manufacturer with multiple operational entities covering forging, heat-treating, machining, quality control finishing, and packaging/warehousing.
