ARP 93-02 Ford 7.3L Power Stroke Diesel Head Stud Kit

ARP Pro Series head studs are chosen by top professional engine builders for all-out competition powerplants. They utilize premium grade 8740 alloy and proprietary ARP2000 alloy steels, which are superior to "aircraft" quality alloy steels. Each stud is heat-treated to 200,000 psi (8740 material) and 220,000 psi (ARP2000 material) and then centerless ground for perfect concentricity. The threads are rolled after heat-treat, providing significantly better fatigue strength compared to studs threaded prior to heat-treat. This manufacturing process ensures precision fitment, with gaskets and cylinder heads gliding into position and aligning perfectly. Each stud is stamped with "ARP" as an assurance of quality.
