To address head gasket failures common in diesel engines used in trucks and RVs, ARP, an industry leader, introduces heavy-duty head studs for popular Ford, Dodge, and GM powerplants. Rated at an impressive 220,000 psi tensile strength, these ARP studs deliver the necessary clamping force to prevent cylinder head lifting under elevated combustion pressures.
Manufactured in ARP's Santa Paula, CA facility from their proprietary ARP 2000 material, the studs undergo thread rolling after heat-treat for optimum fatigue strength. Ensuring perfect concentricity through centerless grinding, the studs feature broached ends for easy installation and cylinder head removal, especially in tight spaces. Each kit includes heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers, all finished with black oxide for enhanced durability.
Choosing the ARP Main Stud Kit for the Ford 7.3L Powerstroke Diesel ('93-'02) is a crucial decision for several reasons. This kit not only addresses main cap walk and fretting but also safeguards your engine block threads. Each kit includes robust parallel-ground washers and premium nuts. Specific applications feature provisions for windage trays, utilizing specially crafted standoff studs with serrated lock nuts for secure tray placement. Crafted from 8740 chrome moly steel and heat-treated in-house to achieve a tensile strength of 200,000 psi, these studs boast precision J-form threads, ensuring a fastener with threads 2000% stronger than alternatives.
