ARP 234-7201 Pro Series Rocker Arm Studs - 3/8-24 16-Piece Kit

ARP Pro Series rocker arm studs are precision-engineered performance components designed to eliminate the wobble and inconsistency found in factory rocker studs. These premium studs feature concentric tolerances within .005" T.I.R. (Total Indicator Reading) from thread pitch to thread pitch, ensuring straight, true installation and consistent rocker geometry across all cylinders.

Key Features:

• Manufactured from premium grade 8740 chrome moly steel for exceptional strength and durability
• Heat-treated to 200,000 psi tensile strength for competition-level reliability
• Precise length specifications ensure positive seating every time
• Extra-large radius base provides greater resistance to flex under high loads
• Tip ground flush for optimum adjuster seating and accurate valve adjustments
• Includes 16 pieces for complete 8-cylinder applications

Application Notes:

Pro Series rocker arm studs are engineered for serious competition applications including drag racing, road racing, and high-performance street engines. The superior material and heat treatment make these studs ideal for high-lift camshafts, heavy valve spring pressures, and elevated RPM operation.

Important Installation Requirements:

• Must be used with ARP's patented Perma-Loc adjusters—not compatible with OEM-style self-locking nuts
• Always verify proper rocker arm stud length for your specific application, especially when using aftermarket pushrods, long-travel valves, or modified installed heights
• Proper installation may require raising rocker arm height to compensate for longer-than-stock components

ARP rocker studs deliver the precision and strength demanded by engine builders who refuse to compromise on valvetrain reliability and performance.
