To overcome head gasket failures that can occur in diesel engines employed in truck and RV applications, industry leader ARP has introduced extra heavy-duty diesel head studs for the popular Ford, Dodge and GM powerplants. These ARP 2504202 diesel head studs are rated at 220,000 psi tensile strength, and provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures. This ARP stud kit is manufactured in ARP’s Santa Paula, CA plant from proprietary ARP 2000 material, with threads rolled after heat-treat to provide optimum fatigue strength. They are centerless ground to assure perfect concentricity. The ends of the ARP 2504202 studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Also included in each ARP stud kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.
