ARP 100-7101 Chevy/ Ford Chrome Moly Rocker Arm Stud 7/16" Shank 180,000 PSI

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 0.005 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. To be used with ARP’s patented Perma-Loc™ adjusters.
