Product Description

Are you looking to overcome head gasket failures? Performance fastener industry leader Automotive Racing Products (ARP) manufactures heavy-duty diesel head studs that will help to reduce or eliminate head gasket failures. They provide the clamping force required to keep cylinder heads from lifting due to higher combustion pressures.

If your diesel will be making extreme horsepower and torque numbers, ARP has created their Custom Age 625+ material for super heavy-duty and professional use. The head stud kits using this metal are tensile strength rated 250,000 – 280,000 psi and are yield strength rated from 235,000 to 255,000 psi. Also, ARP Ultra-Torque Fastener Assembly Lubricant is Included with this kit.


ARP diesel head studs are manufactured in ARP’s Santa Paula, CA plant from proprietary material, with threads rolled after heat-treat to provide optimum fatigue strength. The ARP Bolts are centerless ground to assure perfect concentricity. The ends of the arp bolts head 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 Bolt kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. The ARP Bolts are black oxide finished for extra durability.

In order to ensure optimum quality control for their head studs, bolts, and other products, ARP has grown to be exceptionally self-reliant and now controls all aspects of the manufacturing process. All operations on bolts, head studs, and other products are performed in-house and closely monitored. This is how ARP has been able to establish a reputation for “zero defects” quality for its bolts, head studs, and other products.
