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.
The bottom end of your BMC 4-cylinder engine is subjected to immense forces during operation. To ensure your main caps stay secure and your crankshaft remains properly aligned, Auto Racing Products (ARP) offers this specialized Main Stud Kit. Designed specifically for 2-bolt main configurations, these studs provide significantly more stable clamping than factory main bolts, which is essential for high-performance and racing applications.
ARP main studs are manufactured from premium 8740 chromoly steel and are heat-treated to provide the durability required for high-RPM use. By utilizing studs, you eliminate the stress on the engine block threads caused by the repeated tightening and loosening of bolts, extending the life of your block. The hex nut design ensures easy installation and reliable torque retention. Whether you are building a street-performance engine or a dedicated race motor, these studs provide the foundation for a reliable rotating assembly. Stop worrying about main cap walk and start building with confidence. Explore more high-quality engine internals and fasteners at GGCRACING.
