Chevrolet impala cars use the Rocker Arm to enable movement of the valves in the engine through the valvetrain, after receiving motion from the pushrod. Most of them are made of stamped steel or aluminum and it's function actuates the downward pushrod movement needed for the valves to be opened. In high RPM applications, the main choice for material is aluminum due to the light weight values, while cast iron or forged carbon steel is used in the case of Diesel engines. Throughout the years, Different Rocker Arms' designs used on the Chevrolet Impala models include the conventional Rocker Arms and substantially improved roller Rocker Arms. Roller rockers incorporate bearings that lessen wear so that they are able to suit the overhead valve and the overhead camshaft engines. The rocker ratio varying from 1.5:1 to 1.8:1 in modern engines increases camshaft lift and therefore increases the efficiency of the engines. Newly developed fulcrum bearings are also used to control stress in high-RPM engines and overall durability of the Rocker Arm system in Chevrolet Impala vehicles.
