Premium quality heat-treated 8740 chrome moly steel head stud kits are available for most every domestic and import applications.

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. Some applications have provisions for mounting windage trays and have specially designed standoff studs with serrated lock nuts to position the windage tray and lock it securely in place. 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.

Heat treated, stress relieved, certified 4340 steel 2-piece forgings for increased strength. X-rayed, sonic tested, magna-fluxed, 100% machined with extremely tight tolerances, bronze bushings for floating pins. Excellent for nitrous, turbo/supercharged, and high RPM applications.
