ARP 134-7123 High Performance Rocker Arm Studs 8740 Chrome Moly 2-Piece

ARP High Performance Series rocker arm studs are precision-engineered to eliminate the wobble and inconsistent geometry common with standard rocker studs. Each stud is manufactured to exacting tolerances, with concentricity held within .005" T.I.R. thread pitch to thread pitch, ensuring they install straight and true every time.

Key Features:

• Manufactured from 8740 chrome moly forgings, heat-treated to 180,000 psi tensile strength
• Precision concentricity within .005" T.I.R. for consistent rocker geometry
• Exact length specifications provide positive seating every time
• Extra-large radius base offers superior resistance to flex
• Tip ground flush for optimum adjuster seating
• Includes 2 rocker arm studs

Applications: Ideal for E.T. bracket racing, limited rule oval track competition, and high-performance street use.

Important Installation Notes: These studs are designed for use with ARP's patented Perma-Loc adjusters and should NOT be used with OEM-style self-locking nuts. It is highly recommended to verify the optimum rocker arm stud length for your specific application, particularly when using longer-than-stock pushrods and valves, as rocker arm installed height may need adjustment to compensate for extended components.
