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 ARP 1/2in x 7.5in broached head stud is the gold standard for engine builders requiring precision and strength. Engineered for high-output engines, this stud provides the consistent clamping force necessary to prevent head gasket issues and maintain cylinder seal under extreme boost or high-RPM conditions. Its broached design ensures that installation is straightforward, allowing for accurate torque application every time.
Each stud is manufactured using proprietary alloys that undergo rigorous heat-treating processes. This results in a fastener that is significantly stronger than standard hardware, providing peace of mind during track days or competitive racing.
