ARP 5-16 Rocker Arm Stud Kit Rocker Arm Stud Kit

These Pro series rocker arm studs from ARP are ideal for competition applications. They are made from 8470 chromoly steel and are heat-treated to 200,000 psi tensile strength. These studs are concentric within .005 T.I.R. thread pitch to thread pitch, which will give you more consistent rocker geometry. With an extra-large radius base, these studs are more resistant to flex and will provide a more positive seating. These rocker arm studs were designed for use with Perma-Loc adjusters (not for use with OEM-style, self-locking nuts).
