ARP 235-4016 Cylinder Head Stud Kit Chrome Moly - 8740

The ARP 235-4016 head stud kit delivers professional-grade clamping force and reliability for high-performance engine builds. Manufactured from premium 8740 chrome moly steel and heat-treated to 200,000 psi, these studs provide superior strength and fatigue resistance for demanding applications.

Advanced Manufacturing Process:

• Premium 8740 chrome moly alloy rated beyond aircraft quality standards
• Vertical rack heat-treatment ensures complete and uniform heat penetration to 200,000 psi tensile strength
• Centerless ground after heat-treat for precise concentricity and perfect alignment
• Thread rolled after heat-treatment for 10x better fatigue strength versus pre-heat-treat threading
• Specially undercut shorter studs equalize stretch and clamping force across all fasteners

Performance Benefits:

• Hex head design for reliable torque application
• Superior clamping consistency helps prevent head gasket failure
• Precise tolerances allow cylinder heads and gaskets to align effortlessly during assembly
• Studs stretch only on vertical axis during torquing, eliminating torsional stress found in bolts
• Easier engine assembly and disassembly for racing applications requiring frequent service

Kit Includes:

• Complete head stud set with hardened parallel-ground washers
• High-quality hex nuts for proper torque loading

Each stud is stamped with the ARP logo as verification of authenticity and quality. Designed for serious performance builds where reliability and consistent clamping force are critical to engine longevity and power output.
