ARP 234-4302 Cylinder Head Stud Kit Chrome Moly - 8740 12-Point

The ARP 234-4302 head stud kit delivers professional-grade fastening for high-performance engine builds. Engineered with premium 8740 chrome moly steel and rated at 200,000 psi tensile strength, these studs provide the superior clamping force and reliability demanded by top engine builders in racing and extreme applications.

Key Features:

• 8740 chrome moly steel construction rated at 200,000 psi tensile strength
• 12-point head design for precise torque application
• Thread rolled after heat treatment for 10x better fatigue strength
• Centerless ground for exceptional concentricity and alignment
• Vertical rack heat treatment ensures complete and uniform heat penetration
• Undercut shorter studs equalize stretch for consistent clamping force
• Includes hardened parallel-ground washers for even load distribution

Manufacturing Excellence:

• Cold-forged to ensure molecular integrity
• Heat-treated prior to thread rolling and machining
• Precision centerless grinding through multiple passes for straightness
• Thread rolled post-heat-treat for maximum fatigue resistance

Performance Benefits:

• Superior clamping consistency compared to bolts eliminates twisting forces during installation
• Easier engine assembly with precise cylinder head and gasket alignment
• Undercut design compensates for head gasket compression to prevent blown gaskets
• Studs stretch only on vertical axis during torquing for more accurate load readings
• Ideal for competition engines requiring frequent servicing

ARP Pro Series studs represent the pinnacle of fastener technology for serious performance applications. Each stud is manufactured to exacting tolerances that allow cylinder heads and gaskets to glide into position with perfect alignment. The kit comes complete with hardened washers and meets ARP's zero-defect quality standard. Remember to re-torque after initial engine run to compensate for gasket compression.
