Description

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 extralarge 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. To be used with ARP's patented Perma-Loc adjusters
