Crow Roller Rockers Guide Plates & ARP Stud Kit for Holden V8 253 308 5.0L 7/16”

Crow Cams new stainless steel stud type roller rockers offer virtually zero arm deflection for maximum valve lift and unrivalled resistance to arm breakage. The oversize rocker shafts allow for 7/16 studs to be used without comprising shaft strength. The larger shafts and needle roller bearings also offer greater load capacity for high valve springs pressures. Every set come complete with poly locks for added value and simple, secure valve lash adjustments.

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.
