8740 Chrome Moly Steel Main Studs

The ARP 203-5405 main stud kit is engineered for performance and reliability, addressing critical issues like main cap walk and fretting that can compromise engine integrity. By replacing OEM main bolts with these high-strength studs, you ensure better thread protection within the engine block. Constructed from premium 8740 chrome moly steel, these ARP studs undergo in-house heat treatment to achieve a tensile strength of 200,000 psi. The precision J-form threads are rolled after the heat-treating process, resulting in fasteners that boast threads 1000% stronger than conventional bolts and a significantly longer fatigue life. These features make them a superior choice for competition engines and demanding builds. This specific kit is designed for the 1993-1998 Toyota Supra Twin Turbo models equipped with the L6 2997cc engine. It is crucial to ensure compatibility with your specific vehicle's engine configuration before purchase.
