ARP 205-6002 High Performance Cylinder Head Stud Kit

The ARP 205-6002 cylinder head stud kit delivers the clamping force and reliability demanded by high-performance engine builds. Manufactured from premium 8740 chrome moly steel, these head studs provide superior clamping ability compared to standard head bolts, ensuring consistent head gasket seal under extreme cylinder pressures and temperatures.

Why Studs Over Bolts?

Head studs offer significant advantages over conventional head bolts. Because studs remain stationary during installation, they provide more accurate and consistent torque readings. The stretching action occurs only along the vertical axis, eliminating the torsional stress that head bolts experience during installation. This results in more reliable and even clamping force across the entire head gasket surface.

ARP Manufacturing Excellence:

• Forged in-house from premium 8740 chrome moly steel
• Heat-treated using specialized vertical racks for complete 360-degree penetration
• Threads rolled after heat treatment to provide up to 10 times greater fatigue strength
• Precision CNC-machined to exacting tolerances
• Each fastener features the ARP name stamped as your assurance of quality

8740 Chrome Moly Material:

ARP's 8740 chrome moly steel is a proven quench and temper alloy delivering tensile strengths between 180,000 and 210,000 psi. This material provides excellent toughness and adequate fatigue properties for most high-performance racing applications. The post-heat-treat thread rolling process is critical to achieving optimal fatigue strength, and this is standard practice in all ARP manufacturing.

Kit Includes:

Complete stud kit with high-quality hardened washers and premium ARP nuts for proper installation and optimal clamping force.
