ARP 134-7201 High Performance Rocker Arm Studs Chrome Moly - 8740

ARP High Performance Series rocker arm studs are precision-engineered to eliminate the inconsistent rocker geometry caused by poorly manufactured studs. These studs are manufactured concentric within .005 T.I.R. thread pitch to thread pitch, ensuring they install straight and true every time. Exact lengths provide positive seating, while the extra-large radius base offers superior resistance to flex under high-stress conditions.

High Performance Series Specifications:

• Constructed from 8740 chrome moly forgings
• Heat-treated to 180,000 psi tensile strength
• Tip ground flush for optimum adjuster seating
• Ideal for E.T. bracket racing, limited rule oval track competition, and street performance
• Precision concentricity ensures consistent rocker geometry
• Extra-large radius base minimizes flex

Important Installation Notes:

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

ARP rocker arm studs deliver the precision and strength needed for demanding performance applications where consistent valve train geometry is critical to engine performance and reliability.
