Product Description

SPEED PERF6RMANC3 has worked closely with ARP to develop mainstuds specifically for the Fiesta ST motor. When it comes to making more HP and revving higher and higher, these mainstuds will help to keep the girdle in place so that the crankshaft does not begin to move.

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 2000% stronger than others.
