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.
When building a high-performance engine, the stability of your crankshaft is paramount. Auto Racing Products (ARP) Main Stud Kits are the industry choice for securing main caps in BMC 4-cylinder engines. These studs are engineered to withstand the extreme loads of high-RPM operation, ensuring your main caps do not shift or walk under load. This kit is specifically tailored for 2-bolt main setups, providing a robust solution for engine builders.
Unlike standard bolts, ARP studs are designed to be installed into the block without damaging the threads, allowing for repeated engine teardowns without compromising the block's integrity. The precision-rolled threads ensure consistent torque values, which is critical for maintaining proper main bearing clearances. By upgrading to these studs, you are investing in the long-term health of your engine's rotating assembly. Whether you are restoring a classic BMC engine or pushing the limits of performance, ARP provides the reliability you need.
