4G63 Main Stud Kit By ARP – 207-5401
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. These 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. These 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!

This ARP main stud kit is a must have if you’re building any serious 4G63 setup. The moment you open the box you can tell the quality is on another level. Installed these during my bottom end refresh on my Evo 9 and the engine feels rock solid Torque specs held perfectly and everything seated clean with zero issues of you’re boosting higher or going for real power don’t play around ARP is the truth

Absolutely worth it. I put these ARP main studs in my Evo 8 during a bottom end refresh and the difference in rigidity is real No flex no worries, and perfect fitment. ARP always delivers top tier quality and this kit is no exception
