ARP 235-4114 Cylinder Head Stud Kit Chrome Moly Steel - 8740

The ARP 235-4114 cylinder head stud kit represents the gold standard in engine fasteners, trusted by professional engine builders in all forms of competitive racing. This High Performance 8740 Series kit delivers exceptional clamping force and reliability for demanding applications.

Premium 8740 Chrome Moly Construction:

• Premium grade 8740 chrome moly alloy rated at 200,000 psi tensile strength
• Vertical rack heat-treatment ensures complete and uniform heat penetration
• Thread rolled after heat-treat for 1000% better fatigue strength than pre-threaded studs
• Centerless ground to exacting tolerances for precise concentricity
• Hex head design for reliable installation and removal

Engineering Advantages:

• Studs provide more accurate and consistent torque loading compared to bolts
• Stretch occurs only on vertical axis during torque application, not torsional twist
• Undercut short studs equalize stretch for consistent clamping force
• Compensates for head gasket compression to prevent blown gaskets
• Precision manufacturing allows heads and gaskets to align perfectly during assembly

Complete Kit Includes:

• Application-specific cylinder head studs
• Hardened parallel-ground washers for even load distribution
• Premium hex nuts for proper torque application

Each ARP stud is permanently marked with the ARP logo as your assurance of zero-defect quality. The 8740 Series delivers the strength and consistency required for high-performance street engines and competition powerplants. Re-torque after initial engine run-in to compensate for gasket compression.
