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.
For those running aftermarket cylinder heads on a Big Block Chevy, the Auto Racing Products (ARP) 12pt Head Stud Kit is an essential upgrade. Designed specifically for high-performance applications, these studs provide the consistent, high-torque clamping force necessary to prevent head gasket failure in high-compression or forced-induction engines. The 12-point nut design allows for easier socket access, making installation and maintenance much more efficient.
By switching to studs, you eliminate the risk of stripping block threads, a common issue when using bolts in aluminum or high-performance cast iron blocks. This kit provides the peace of mind that your engine will remain sealed, regardless of the power levels you are pushing. Whether you are building a drag car or a high-output street engine, these studs are the foundation of a reliable build. Get the best in engine hardware from GGCRACING.
