ARP 235-7206 Pro Series Rocker Arm Studs - Chrome Moly Steel

ARP Pro Series rocker arm studs are precision-engineered for competition applications where accuracy and strength are critical. Unlike standard rocker studs that wobble during installation, ARP studs are manufactured to exacting tolerances—concentric within .005" T.I.R. thread pitch to thread pitch—ensuring they install straight and true for consistent rocker geometry.

Key Features:

• Premium grade 8740 chrome moly steel construction
• Heat-treated to 200,000 psi tensile strength for competition use
• Precision concentricity within .005" T.I.R. for accurate rocker geometry
• Exact lengths ensure positive seating every time
• Extra-large radius base provides greater resistance to flex
• Tip ground flush for optimum adjuster seating

Important Installation Notes:

• Not compatible with OEM-style self-locking nuts
• Must be used with ARP's patented Perma-Loc adjusters
• Determine optimum stud length for your application, especially when using longer pushrods or valves
• Consider raising rocker arm installed height when using longer-than-stock components

ARP's Pro Series rocker studs deliver the precision and durability demanded by serious racers and engine builders, providing reliable performance in high-stress competition environments.
