Function of the Rocker Arm in Chevrolet Tracker cars is to assist in the valvetrain of the engine moving from the pushrod to the valves of intake and exhaust. Most of these parts are made from stamped steel or aluminum and essentially actuate a movement of pushrod in a vertical direction and this moves the valves down as required. Valvetrain components use aluminum that is light, and although generally diesel engines use cast iron or forged carbon steel, in the high RPM of many small engines, aluminum can be employed. Different kinds of outer linkages, particularly roller rockers, include needle bearings to decrease the amount of rubbing and thus enhance performance over a period when compared to basic types. The contemporary motors use the rocker ratio ranging between 1.5:1 and 1.8:1 to increase the camshaft lift and in this way to enhance the performance. Better fulcrum bearings are also used in the high RPM engines to deal with stress and to enhance the durability of the rocker arm system to allow them work efficiently.
