ARP (Automotive Racing Products) makes the strongest fasteners in motorsport — head studs, main studs, rod bolts, and flexplate bolts used by every Formula 1, NHRA, NASCAR, and championship motorsport program. Aerospace-grade alloys, exact-fit machining.
Ensure your crankshaft remains stable under load with this Auto Racing Products (ARP) Main Bolt Kit. Specifically designed for 351C 2-bolt main blocks, these high-performance series bolts are a direct upgrade over factory hardware. They provide the necessary clamping force to minimize main cap walk and ensure proper bearing clearance during high-RPM operation.
When building a performance engine, the main caps are the foundation of your rotating assembly. Using high-quality ARP fasteners ensures that the main caps are held securely, preventing the micro-movements that can lead to catastrophic bearing failure. These bolts are cold-forged and heat-treated to ensure they exceed OEM strength specifications, providing a reliable solution for both street and strip engines. The black oxide finish provides excellent rust resistance, ensuring these bolts maintain their integrity over the life of the engine. Upgrade your bottom end with confidence using hardware from GGCRACING.
