Description

The ARP CA625+ head stud kit is designed to provide superior clamping force for cylinder heads on high-performance engines, preventing head lift under high combustion pressures. It's an upgrade over factory fasteners not designed for performance use. The CA625+ material is a high-strength, super-alloy that offers excellent fatigue life, tensile strength, and resistance to corrosion and oxidation. Each stud is heat-treated for molecular integrity, centerless ground for perfect concentricity, and features broached ends for easy installation.
