Their roller tip is more efficient than standard scrub-type rockers, they have a lower mass moment of inertia (less weight on the valve), and come in ratios that will increase the net valve lift and duration of a camshaft.
The rocker arms are manufactured from heat-treated billet aluminium extrusions, and CNC machined to exacting tolerances. These gold anodized rockers have long had the reputation of being the most accurate on the market and feature Crane's exclusive Quick-Lift™technology. They employ heavy-duty precision-ground steel needle bearings, a heat-treated steel roller tip, and come complete with adjustable locking nuts.
