These ARP studs boast a robust 220,000 psi tensile strength, delivering the necessary clamping force to prevent cylinder head lifting under heightened combustion pressures. Manufactured at ARP's Santa Paula, CA plant, they utilize the proprietary ARP 2000 material, with threads rolled after heat-treat to ensure optimum fatigue strength.
Precision centerless grinding guarantees perfect concentricity, while broached ends facilitate easy installation and removal of the cylinder head, especially in confined spaces. Each kit includes heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers, all finished with black oxide for enhanced durability.
