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 build maintains consistent clamping force with Auto Racing Products (ARP) cylinder head insert washers. Designed for high-performance applications, these 7/16 ID x .875 OD washers are essential for protecting cylinder head surfaces and ensuring accurate torque readings during assembly. Whether you are building a street machine or a dedicated track car, these washers provide the stability required under extreme thermal stress.
These washers are manufactured to exacting tolerances, preventing the galling or sinking often seen with inferior hardware. By distributing load effectively, they help maintain the integrity of your head gasket seal, preventing leaks and compression loss. The chromoly construction offers superior fatigue resistance compared to standard steel alternatives, making them a staple for any serious engine builder. Trust in the quality of ARP components to keep your valvetrain and cylinder head secure under high-RPM conditions. Find all your essential engine hardware and performance upgrades at GGCRACING.
