ARP fasteners outperform the competition through uncompromising manufacturing. Made from premium 8740 alloy and heat-treated to 200,000 psi, they feature deep, uniform heat penetration instead of cheap bulk processing. Ten precise centerless ground cuts guarantee near-perfect straightness. By rolling the threads after heat treatment, ARP incurs higher tooling costs but delivers 1,000% greater fatigue strength than standard industry studs.
Compatible with 93-98 Toyota Supra NA (2JZ-GE) & Twin Turbo (2JZ-GTE) as well as 1JZ-GTE
Fits both VVTi and Non-VVTi
