Headstud kit for the 94-02 7.3L PowerStroke Diesel.

Tough enough for NASCAR.
ARP cylinder head stud kits are precision centerless-ground and thread-rolled to Mil-S-8879 specs. Their black oxide finish protects them from wear and corrosion, and ARP throws in hardened parallel washers for uniform load distribution and accurate torque readings.

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 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 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. Also included in each kit are heat-treated, chrome-moly steel 12-point nuts and parallel-ground washers. They are black oxide finished for extra durability.

Ford 7.3L Main Stud Kit

There are many important reasons to use ARP main stud kits, including the elimination of main cap walk and fretting, as well as protecting the threads in your engine block. All kits come complete with hardened parallel-ground washers and high quality nuts. The studs are manufactured from 8740 chrome moly steel, heat-treated in-house to 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.

Keep your intake in place and prevent leaks.
ARP's rugged, black-oxide coated chromemoly intake manifold bolts are rated at 170,000 psi. They're precision-machined for optimum thread engagement, and have a wide-area flange for better load distribution. They also feature precision-rolled threads, which prevent galling while promoting more consistent torque loading. These bolts are available with either hex or 12-point heads, and washers are included.
