ARP 234-4301 Pro Series Cylinder Head Stud Kit Small Block Chevy

ARP Pro Series cylinder head studs are engineered for serious performance applications, featuring premium grade 8740 chromoly alloy that is heat-treated to 200,000 psi tensile strength—far exceeding standard Grade 8 hardware. Each stud undergoes a vertical heat-treat process in specialized racks to ensure complete and uniform heat penetration throughout the component.

Superior Manufacturing Process:

• Centerless ground after heat-treat for exceptional concentricity and precision fit
• Thread rolled after heat-treatment for approximately 1000% better fatigue strength compared to studs threaded before heat-treat
• Precision tolerances allow cylinder heads and gaskets to align perfectly during installation
• Heat-treated to 200,000 psi for maximum clamping force and reliability

Complete Kit Includes:

• Premium quality parallel ground washers for even load distribution
• Compact 12-point style nuts for easier access in tight spaces
• All hardware needed for complete installation

Application: Designed for select small block Chevrolet applications including 23-degree OEM cast iron and aluminum heads, Gen III Vortec/Truck engines, and popular aftermarket cylinder heads from Airflow Research, Brownfield, Brodix (-8, -10, -11, Track I), Dart (Sportsman and Dart II), Edelbrock, and Trick Flow. These studs are the preferred choice of professional engine builders for high-performance and competition powerplants where reliability and maximum clamping force are critical.
