Product Information
To overcome head gasket failures that can occur in diesel engines in truck and RV applications, the industry leader ARP has introduced extra heavy-duty head studs for the popular Ford, Dodge and GM powerplants. These ARP 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. The studs are manufactured in The USA at 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 studs are broached to facilitate easy installation. This feature also enables the cylinder head to be removed in tight quarters. Each kit includes heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability. This set is part number 2504203 for the Ford 07-08 6.4L Powerstroke Diesel Engine.
