ARP 7/16" Rocker Arm Studs - (Extra Long)
These "Pro series" rocker arm studs from ARP are ideal for competition applications. They are manufactured from 8470 chromoly steel and 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 ARP rocker arm studs were designed for use with Perma-Loc adjusters, not for use with OEM-style, self-locking nuts. This extra long stud is a perfect replacement for standard length studs where a longer poly-lock engagement is required.
