ARP main studs are manufactured from 8740 chrome-moly steel, heat-treated in-house, 200,000 psi tensile strength and precision J-form threads rolled after heat-treat to create a fastener that has threads 1000% stronger. All kits come complete with ten hardened parallel-ground washers and ten aerospace grade nuts. Reduce crankshaft flex and main cap fatigue with these premium quality main studs. Don't settle for anything less than the best! If you've increased your horsepower significantly, upgrade to our Main Cap Stud Set for added strength and reliability.
NOTE: These studs are utilized on the main cap bolts to secure your crankshaft, not your cylinder head. If you need cylinder head studs, see Part #: 1024069.
