ARP 100-7121 "High Performance" Rocker Arm Stud Kit
Fits most small block Chevrolet engines with screw-in rocker studs

ARP's high quality rocker arm studs are concentric within .005" thread pitch to thread pitch so they run in straight and true. And the lengths are exact so they provide positive seating every time and an extra large radius on the base gives them much better resistance to flexing. All of ARP's rocker studs are made from 8740 chrome moly steel alloy and heat treated to 180,000 psi. The "High Performance" series is excellent for bracket racing, limited rules circle track racing, and high performance street use while the Pro Series studs are excellent for standing up to the harsh demands of competition.


Upper thread: 3/8-24, lower thread: 7/16-14
These studs are not to be used with OEM-style self-locking nuts.
Use only ARP "Perma-Loc" adjusters, sold separately.
