One of the significant parts in the Chevrolet Monte Carlo vehicles is the Rocker Arm, which plays an essential role in valvetrain system, where the motion of pushrod is provided to the valves such as the intake and exhaust. Traditionally made of stamped steel or aluminum, these rocker arms transfer lateral pushrod oscillation into the desired up and down movement to open the valves. For highly rpm applications aluminum is used since it is light whereas for durability cast iron or forged carbon steel is used in diesel engines. Rocker arms on Chevrolet Monte Carlo may vary in type such as the traditional rocker arms and roller rocker arms. Roller rockers, which incorporate needle bearings decrease friction and thus wear making the performance of these rockers better as opposed to others. The rocker ratio, that is between 1.5:1 and 1.8:1 in modern engines, enables the camshaft to produce higher lift and hence better performance of the engine. Better fulcrum bearings are also used in Chevrolet Monte Carlo car engines with high RPM levels to cater for the stress and prolong the durability.
