Ford 289-302 2 bolt - HP Series Studs
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.
The studs are manufactured in our own factory using the best materials, processes,
designs and engineering. Every ARP main stud kit exceeds the most stringent aerospace
specifications. All kits come complete with hardened parallel-ground washers and
aerospace 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 190,000 PSI tensile strength, and precision J-form threads rolled
after heat-treat to create a fastener that has threads 1000% stronger than others. Don't
settle for anything less than the best. Insist on genuine ARP studs . . . you'll find the
name stamped right on the end!
