Have you have ever installed a rocker stud 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.

NOTE:These studs should be used with ARPs patented Perma-Loc adjusters ONLY. Theyare not to be used with OEM-style, self-locking nuts.
