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 vehicle's critical components stay secure with this set of five 5/16-18 x 4.000-inch 6-point bolts from Auto Racing Products. Designed for builders who demand precision and strength, these bolts are forged from high-tensile chromoly steel. The black oxide finish provides a sleek look while offering essential protection against rust and oxidation in harsh under-hood conditions.
The 4-inch length makes these an essential addition to any mechanic's toolbox, offering the reach needed for complex assemblies. Unlike standard hardware store bolts, these racing-grade fasteners are heat-treated to resist stretching and fatigue, ensuring your setup remains consistent pass after pass. Whether you are securing heavy-duty accessories or structural components, these bolts deliver the reliability required for competitive motorsports. Elevate your build quality with professional-grade hardware from GGCRACING.
