ARP 134-7124 Rocker Arm Stud Kit for 3/8 Rocker Arm Stud Kit (Note 6) ymm_21 Interchangeable black and white faceplatesIf 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.
