Description
Upgrade your engine’s durability with the ARP Pro Series Head Bolt Kit for Volkswagen and Audi 1.8T engines. Unlike factory torque-to-yield bolts that must be replaced after each use, ARP head bolts are reusable and designed for superior strength and longevity. Manufactured from premium 8740 chromoly alloy steel and heat-treated to a tensile strength of 200,000 psi, these bolts provide unmatched clamping force to prevent head lift and gasket failure—especially in high-compression or turbocharged applications.
Each bolt is precision centerless-ground and thread-rolled after heat treatment for optimal fatigue resistance and consistent torque readings. Finished with black oxide for corrosion protection, this kit includes hardened parallel-ground washers for even load distribution and reliable head sealing. A must-have upgrade for any performance or rebuilt engine.
