ARP 234-3602 ARP2000 Hex Head Bolt Kit for 2004-Up Small Block Chevrolet

Fits 2004-up Small Block Chevrolet (LS-series) engines.

The ARP 234-3602 Head Bolt Kit is engineered for high-performance builds where superior clamping force is mandatory to maintain a reliable head gasket seal. Unlike standard 8740 chromoly, this kit is manufactured from ARP2000 alloy, which is heat-treated to a tensile strength of 220,000 psi. This makes it an ideal upgrade for high-compression, turbocharged, or supercharged applications that exceed the limits of factory torque-to-yield fasteners.

These fasteners feature a traditional hex head for easy tool engagement and are designed specifically for the 2004 and later engine blocks that utilize equal-length head bolts. Each kit includes premium parallel-ground washers to ensure even load distribution and accurate torque readings during installation. Because these are high-quality ARP fasteners, they are fully reusable, unlike one-time-use OE bolts.
