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, every component matters. The ARP 1/2 x 6.5in broached individual stud is designed for builders who demand reliability and superior clamping force. Manufactured from premium-grade alloys, these studs are heat-treated to ensure they withstand the extreme pressures and thermal cycling of racing environments.
The broached design allows for precise installation and removal, providing a significant advantage over standard hardware. Whether you are replacing a single damaged stud or completing a custom assembly, ARP hardware provides the consistency required for professional-grade results. These studs are engineered to prevent head gasket failure and maintain structural integrity under boost or high-compression conditions.
At GGCRACING, we stock a wide selection of individual ARP fasteners to ensure you have the exact hardware needed for your specific engine configuration. Don't settle for inferior fasteners when building your engine; choose the industry leader in automotive hardware to ensure your build stays together under the most demanding conditions.
