Application: Most stock small block chevy engines with 7/16" screw in studs.
If you have ever installed a rocker stud into a cylinder head and watched it wobble as it screwed in – you knew from the beginning that the rocker geometry was going to be inconsistent all over the place. ARP rocker studs are concentric within .005 T.I.R. thread pitch to thread pitch. They run-in straight and true. Lengths are exact – designed to provide positive seating every time. An extra-large radius base offers greater resistance to flex.
ARP's High Performance Series bolts are made of 8740 chrome moly forgings and heat-treated to 180,000 psi. Excellent for E.T. Bracket Racing, limited rule oval track competition and street use. Tip: ground flush for optimum adjuster seating.
Don't take any chances with the safety of your street machine or race car, insist on the special bolts and fasteners developed by the engineers at ARP!
