Crane Cams Energizer Rocker Arm for Ford V8 Engine, (Set of 16) features ordinary stamped steel (or in some instances cast iron) rockers. They rotate on a pivot ball and have substantial friction, while also "scrubbing" the tip of the valve. The roller lifters have both a roller bearing fulcrum and a roller tip, significantly improving efficiency. Crane's aluminum roller rocker arms also reduce valve train weight - especially mass moment of inertia (which is what impacts the valve springs and RPM potential). The aerospace quality aluminum alloys used by Crane also provide an excellent strength-to-weight benefit. The Ford Motor Company selected Energizer rocker arms for their Cobra V-8 production engines and backed them with a full factory warranty.
