ARP 300-2409 Cylinder Head Stud Kit

ARP's cylinder head studs are engineered to provide superior clamping force and reliability compared to traditional head bolts. These precision-manufactured fasteners are designed to maintain consistent torque and prevent head gasket failure, even under extreme cylinder pressures and temperatures.

Key Features:

• Manufactured from premium 8740 chrome moly steel for exceptional strength
• Heat-treated to 200,000 psi tensile strength for maximum clamping force
• Precision rolled threads after heat-treat provide superior fatigue resistance
• Black oxide finish for corrosion protection
• Includes hardened parallel-ground washers and high-quality nuts
• Thread engagement extends into the engine block for optimal load distribution

ARP head studs allow for more accurate and consistent torque readings because the fastener is not twisted during installation like a conventional head bolt. This results in more uniform clamping loads across the head gasket surface, reducing the risk of gasket failure and improving engine sealing. Each kit includes detailed installation instructions and recommended torque specifications.
