45 kits found for Rocker Arm Studs

ARP rocker studs are concentric within .005˝, extra-large radius base offers greater resistance to flex. NOTE: To be used ONLY with ARP’s patented Perma-Loc™ adjusters.

HIGH PERFORMANCE SERIES - 8740 chrome moly forgings, heat-treated to 180,000 psi, tip ground flush for optimum adjuster seating

PRO SERIES - made of premium grade 8740 chrome moly steel, heat-treated to a tensile strength of 200,000 psi

IMPORTANT TECH NOTE - it is highly advisable to determine what the optimum rocker arm stud length is for your particular application. This is especially true when “long” pushrods and valves are employed – you should raise the “installed height” of the rocker arm to compensate for the longer-than-stock components.

(2) Fits most stock SBChevy with 3/8 screw-in studs (3) Fits most stock SBChevy with 7/16 screw-in studs (4) Fits most stock BBChevy with 7/16 screw-in studs (5) Fits most SBFord with 7/16 screw-in studs (6) Fits most SBFord with 3/8 screw-in studs
