Product Description

The ARP 207-5801 main stud kit is engineered for Mitsubishi 6G72 3.0L V6 engines found in the 3000GT, Dodge Stealth, Diamante, Eclipse, and other applications. This kit addresses the common issue of main cap walk and fretting that occurs with factory bolts, providing a substantial upgrade for both stock rebuilds and high-performance engine builds. Unlike bolts that twist during installation and can yield inconsistent clamping force, studs thread into the block and allow the nut to apply pure tensile load for more accurate torque readings and superior cap alignment. The studs are manufactured from premium 8740 chromoly steel and heat-treated in-house at ARP's facility to achieve 190,000 PSI tensile strength. The precision J-form threads are rolled after heat-treating, a process that creates threads approximately 2000% stronger than fasteners threaded before heat-treat. Each stud is centerless-ground and thread-rolled to Mil-S-8879 military specifications with a black oxide finish for corrosion resistance. The kit includes hardened parallel-ground washers that distribute clamping load evenly across the main caps, plus high-strength hex nuts and ARP Ultra-Torque assembly lubricant for proper installation. This main stud kit is an essential component for turbocharged 6G72 builds and any application where bottom-end reliability is critical.
