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 engine stays sealed under extreme pressure with the ARP 100-7531 Valve Cover Bolt Kit. Engineered specifically for the 2001-2004 Chevy and GMC 6.6L LB7 Duramax diesel engines, this kit provides the superior clamping force and reliability that professional engine builders demand. Unlike standard factory hardware, these ARP bolts are manufactured from high-grade 8740 chromoly steel, offering significantly higher tensile strength to prevent loosening or snapping during heavy-duty operation.
Whether you are performing a routine maintenance overhaul or a high-performance engine build, these bolts offer peace of mind against oil leaks and hardware failure. The 12-point design allows for better socket engagement, reducing the risk of rounding off bolt heads during high-torque applications. Trust your diesel build to the industry standard in fastener technology. Find all your essential engine hardware upgrades at GGCRACING.
