Crane Cams billet extruded aluminum rocker arms have been racings most popular aluminum rockers since 1964. Their roller tip is more efficient than standard scrub-type rockers, they have a lower mass (less weight on the valve), and come in ratios that will increase the net valve lift and duration of a camshaft.
The Gold Race rocker arms are manufactured from heat-treated billet aluminum extrusions, and CNC machined to exacting tolerances. They feature Crane's exclusive Quick-Lift technology and employ heavy-duty precision-ground steel needle bearings, a heat-treated steel roller tips.
