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 precise clamping force with these Auto Racing Products head bolt insert washers. Designed for demanding racing applications, these washers provide the necessary load distribution for your cylinder head bolts, preventing damage to the head surface and ensuring a consistent torque reading during engine assembly.
These washers are manufactured from premium chromoly steel, offering superior structural integrity compared to standard hardware. The black oxide finish provides a durable barrier against the harsh environment of an engine bay. Whether you are building a high-compression naturally aspirated engine or a forced-induction powerhouse, using the correct hardware is critical to engine longevity. The insert design helps center the bolt and protect the cylinder head from galling during the tightening process. At GGCRACING, we prioritize high-quality fasteners to ensure your engine build meets professional standards every time you hit the track.
