Automotive Racing Products (ARP) Rocker Arm Stud Set 134-7201; High Performance Screw-In w/ Hex Shoulder 3/8 in. -24 2.350 in. Black Oxide 8740 Chromoly for Chevy SBC Vortec

ARP High Performance series rocker arm studs are ideal for E.T. bracket racing, limited rule Oval Track competition, and street use. They are made from 8740 chromemoly steel and are heat-treated to 180,000 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 are designed to be used with Perma-Loc adjusters (not for use with OEM-style, self-locking nuts).
