Product Information
There are many 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 suds are manufactured in ARP's 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 to 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(Stay bolts are 200,000 psi), 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 C3 Motorsports kit is a must for the 2-Bolt VR-4 / Twin Turbo main block. These ARP's are cold-forged with a 190,000 psi rating!
We have installed these kits in several TD05 and T3/T4 cars with great results. C3 is also running this kit in our 3.2L T3/T4 track car!
This replaces the 8 longer Main Bolts and the 4 smaller stay bolts that bolt into the block.
