ARP 235-4316 High Performance Cylinder Head Stud Kit Chrome Moly - 8740

The ARP 235-4316 cylinder head stud kit delivers professional-grade engine fastening using premium 8740 chrome moly alloy rated at 200,000 psi. Trusted by top engine builders in competitive racing, these studs provide superior clamping force and reliability for high-performance applications.

Premium Manufacturing Process:

• 8740 chrome moly steel construction rated at 200,000 psi tensile strength
• Vertical rack heat-treating ensures complete and consistent heat penetration
• Centerless ground after heat-treat for exceptional concentricity and straightness
• Thread rolling performed after heat-treat provides 10x better fatigue strength
• 12-point head design for positive engagement and accurate torque application
• Specially undercut short studs equalize stretch for consistent clamping force

Key Benefits:

• Precise tolerances allow cylinder heads and gaskets to align and install smoothly
• Studs eliminate twisting forces during installation for more accurate torque readings
• Reduced wrenching profile with wide-area flanged head design
• Helps prevent head gasket failure through optimized clamping consistency
• Includes hardened parallel-ground washers for even load distribution

ARP studs are manufactured to exacting standards that exceed aerospace quality requirements. Each stud is marked with the ARP stamp as assurance of zero-defect quality. The stud design allows for easier engine assembly compared to bolts, as studs stretch only on the vertical axis when torqued, providing more consistent clamping force. Ideal for racing engines that require frequent service and absolute reliability.

Note: Studs should be installed finger-tight in a relaxed mode. Re-torque after initial engine operation to compensate for head gasket compression.
