Description

Pro Series ARP2000 main stud kit for 2008 and later Mitsubishi 2.0L (4B11) Turbo and Non Turbo applications. Part No. 207-5403 includes a set of ten, M10 ARP2000 main studs, a set of ten, M8 ARP2000 main studs, twenty 8740 chrome moly steel 12 pt nuts and a 1/2 oz. pack of ARP Ultra-Torque fastener assembly lubricant. All Pro Series ARP2000 studs are centerless ground, heat treated prior to thread rolling and machining, and are nominally rated at 220,000 psi. These fasteners deliver a 50% increase in tensile strength over the OEM main bolts.

ARP main stud kit for Mitsubishi Evolution X / Ralliart 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 200,000 psi tensile strength, and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger than others.
