Automotive Racing Products (ARP) started in 1968, in Southern California. Their product line includes everything from engine and driveline fasteners for OEM replacement parts to exotic specialty hardware for the Formula 1, Indycar, NASCAR, NHRA Drag Racing, and Marine Applications. They produce a number of specialty products like cylinder head fastener kits, connecting rod bolts, exhaust manifold/header fastener kits, oil pan fastener kits, piston ring compressors, and more.

These ARP High Performance series head bolt kits are tough! They are rated at 170,000 psi--15 percent stronger than Grade 8 fasteners. They come available with hex heads or reduced wrenching 12-point heads that eliminate the need for valvetrain removal when re-torquing cylinder heads. Designed to fit cast iron factory-style cylinder heads.
