Aluminum, and stamped steel rocker arms that will upgrade your valve train.
| PROFORM roller rockers reduce valvetrain friction and add effective lift across one of the widest application ranges in the aftermarket: small block Chevrolet Gen 1 and Vortec, big block Chevrolet, GM LS, Ford 302HO/351W and Boss 351C/429–460, Chrysler small and big block, Oldsmobile 350–455, and Buick 455. Choose extruded aluminum for street/strip value, billet aluminum for maximum strength, or steel where budget rules, in ratios from 1.5 to 1.73 — with self-aligning and pedestal-mount designs where the heads call for them. Roller tips and needle-bearing fulcrums cut wear at the valve stem. |
