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. The solution? ARP quality. ARP rocker studs are concentric within .005 T.I.R. thread pitch to thread pitch. They run-in straight and true, and the extra-large radius base offers greater resistance to flex. Lengths are exact -- designed to provide positive seating every time. These High Performance series rocker arm studs are made of 8740 chrome moly forgings, heat-treated to 180,000 psi, and the tips are ground flush for optimum adjuster seating. ARP's patented Perma-Loc adjusters (available separately) should be used, not OEM-style self-locking nuts. 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. The dimensions for these studs are: 1.750 overall stud height, .700 screw-in thread depth, .800 adjuster thread depth, 3/8-24 shank diameter and thread, and 7/16-14 base diameter and thread.
