Rocker Arm Studs, 8740 Chromoly, Fits Chevy 4.3L V6 Vortec Cylinder Heads, Pair

ARP High Performance Series rocker arm studs are ideal for ET bracket racing, limited rule oval track competition, or street use. Made from 8740 chromoly steel and are heat-treated to 180,000 psi tensile strength, they 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, they are more resistant to flex and will provide a more positive seating. These rocker arm studs are designed to be used with Perma-Loc adjusters (not for use with OEM-style, self-locking nuts).
