ARP 233-4301 Head Stud Kit Chrome Moly Steel - 8740 12-Point

The ARP 233-4301 Head Stud Kit delivers professional-grade cylinder head clamping performance using premium 8740 chrome moly steel construction. Engineered for high-performance and racing applications, this kit features 12-point studs that are precisely manufactured to exacting tolerances for superior strength and reliability.

Advanced Manufacturing Process:

• Premium 8740 chrome moly alloy rated at 200,000 psi tensile strength
• Vertical rack heat-treatment ensures complete and uniform heat penetration
• Centerless ground after heat-treat for exceptional concentricity and straightness
• Thread rolling performed after heat-treat for 10x better fatigue strength
• Undercut shorter studs equalize stretch for consistent clamping force

Key Benefits:

• Superior clamping force helps prevent head gasket failures
• Precision tolerances allow cylinder heads and gaskets to align perfectly during assembly
• 12-point head design provides excellent grip and reduces rounding risk
• Studs provide more accurate torque loading than bolts by eliminating torsional stress
• Includes hardened parallel-ground washers for even load distribution

Each ARP stud is manufactured to strict quality standards and stamped with the ARP logo as your assurance of zero-defect performance. This stud kit is ideal for engines requiring frequent service or those subjected to extreme cylinder pressures in competition environments.

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