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.
Ensure your exhaust system stays sealed under extreme heat and vibration with the Auto Racing Products stainless steel header bolt kit. Engineered specifically for Big Block Chevy applications, these 3/8-16 thread bolts provide superior clamping force compared to standard factory hardware. The polished stainless steel construction offers excellent corrosion resistance, ensuring your engine bay looks as good as it performs.
These bolts are designed to withstand the thermal expansion cycles common in high-performance engines, preventing header leaks that can rob your vehicle of power. The precise length ensures optimal thread engagement without bottoming out in the cylinder head. Whether you are building a street machine or a dedicated track car, choosing the right fasteners is critical for long-term reliability. Trust the engineering excellence found at GGCRACING for your next engine build.
