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 applications demanding longer reach and uncompromising strength, these Auto Racing Products 4-inch bolts are the gold standard. Engineered from high-tensile chromoly steel, these fasteners are specifically designed to handle the high-stress environments of professional racing. The 7/16-14 thread pitch combined with a 4-inch length makes them perfect for deep-reach mounting applications in engine bays, chassis fabrication, and suspension setups.
The 6-point hex head is engineered for maximum torque transfer, allowing you to tighten these fasteners securely without the risk of stripping or rounding. The black oxide finish provides excellent corrosion resistance, ensuring these bolts remain functional and easy to remove even after exposure to harsh track conditions. By choosing chromoly over standard steel, you are investing in a fastener that resists stretching and fatigue, providing consistent clamping force throughout the life of your build. Whether you are a professional fabricator or a dedicated DIY enthusiast, these bolts offer the reliability you need for your most demanding projects. Find these and other premium racing components at GGCRACING.
