'89-'98 Dodge 12V 12mm ARP Custom Age 625+ Head Stud Kit

With performance enthusiasts adding increasing amounts of turbo boost to diesel applications, ARP® has provided an extra measure of security in the form of extra-strong head studs manufactured from the firm’s proprietary Custom Age 625+® material that has a minimum rating of 260,000 psi tensile strength. They are engineered to provide the clamping force required to keep cylinder heads from lifting due to exceptionally high combustion pressures.

ARP Custom Age 625+ head stud kits are available for the popular 5.9L &6.7L Dodge/Cummins diesel for both the 12-valve (p/n 247-4205) and 24-valve (p/n 247-4204) models. ARP also offers head stud kits made from ARP2000 (220,000 psi minimum) for the Dodge/Cummins. The stud kits include heat-treated chrome moly steel nuts (12-point) and parallel-ground washers.

The studs are manufactured in ARP’s Santa Paula, CA plant, 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.
