ARP 3/8" Rocker Arm Studs - (Standard)
These "Pro series" rocker arm studs from ARP are ideal for street and track applications. They are manufactured from 8740 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.
