ARP 207-5401 Main Stud Kit for MITSUBISHI 4G63 / 4B11

2-Bolt Main Stud Kit by ARP. 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 Chromoly 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.
