Product Details

ARP High Performance Series rocker arm studs deliver precision-engineered stability and consistency for demanding engine applications. Each stud is manufactured to exacting tolerances, with concentricity within .005 T.I.R. thread pitch to thread pitch, ensuring straight, true installation without wobble. Exact lengths provide positive seating every time, 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
  • 2-piece set

Important Installation Notes:

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

ARP rocker studs eliminate the guesswork in rocker geometry, providing consistent performance across all cylinders. The precision manufacturing ensures reliable valve train operation under the high loads of performance and racing applications.
