| ARP Fasteners are the highest quality in the industry. ARP's automotive racing fasteners are precision made using certified SDF or CHQ quality material (better than aircraft-quality). ARP Fasteners are used by leading teams in nearly every form of racing, from IndyCar to Formula 1. These super high strength fasteners are made in Southern California. ARP main studs and head studs provide 190,000psi tensile strength. All stud kits come complete with parallel-ground washers and aerospace quality nuts. ARP rod bolts provide 190,000 to 220,000psi tensile. That's at least 40% stronger than original types! Threads are rolled to Mil-Specs after heat treatment, ensuring the best possible fastener. | |
