ARP Toyota Supra B58B30 Main Stud Kit

This ARP Main Stud Kit replaces the factory main-cap fasteners on the Toyota Supra B58B30 (and BMW B58) turbo inline-six with high-strength studs for more accurate, repeatable clamp load and better main-bearing support under boost and high rpm. Includes studs, hardened parallel-ground washers, and nuts.
