3/8" Typical SBC; Cold Forged; Full Set of 16
If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in – you knew from the beginning that the rocker geometry was going to be inconsistent all over the place. ARP rocker studs are concentric within .005 T.I.R. thread pitch to thread pitch. They run-in straight and true. Lengths are exact – designed to provide positive seating every time. An extra-large radius base offers greater resistance to flex. Available in both High Performance and Pro Series models. NOTE: Not to be used with OEM-style, self-locking nuts. These studs work great with ARP Perma-Loc® Rocker Arm Adjusters.
All Pro Series bolts are cold-forged to ensure molecular integrity, heat-treated prior to thread rolling and machining, and meet the ARP “ZERO defect – ZERO failure” quality standard.

It is highly advisable to determine what the optimum rocker arm stud length is for your particular application. This is especially true when “long” pushrods and valves are employed - you should raise the “installed height” of the rocker arm to compensate for the longer-than-stock components.
