ARP UnderCut Head Stud Kit 12pt For 1987-1992 Supra MK3 3.0L 7MGE/7MGTE

Designed for high-performance Toyota JZ-series engines, the ARP 1987–1992 Supra MK3 Undercut Head Stud Kit delivers unmatched strength and precision. Made from premium 8740 chromoly steel, each stud is heat-treated to 190,000 psi, then thread rolled after heat-treat for 2000% better fatigue strength. The undercut design helps equalize stud stretch, providing more consistent clamping force and minimizing the risk of blown head gaskets. Whether on the street or track, ARP ensures your cylinder heads stay perfectly sealed under extreme pressure.

This ARP Pro Series kit includes black oxide-finished studs, 12-point nuts, and hardened parallel-ground washers for maximum torque accuracy and even load distribution. Studs are centerless ground for superior concentricity, allowing for effortless head and gasket alignment. Trusted by top engine builders worldwide, ARP fasteners are the gold standard for serious performance builds. When engine reliability and longevity matter, this kit is the perfect upgrade for your MK3 Supra.
