ARP 334-7204 Rocker Arm Stud Kit 7/16 Rocker Arm Stud Kit ymm_1 850˝ Thread Size 5/16-18 washersIf 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.
