The Rocker Arm in Pontiac Grand Prix cars is an imperative component of the machines' valvetrain system because of its function in the conversion of the motion of the pushrod to the operation of the intake and exhaust valves. Made in stamped steel or aluminium for most automotive engines, these rocker arms work to turn an up-and-down pushrod movement into the appropriate amount of force required to lift the valves. Lightweight applications such as those involving high engine RPM range favour aluminum while cast iron or forged carbon steel is used in diesel engines for better durability. Different types of Rocker Arms have been used in Pontiac Grand Prix cars and these are metallic to metallic rocker arms and the roller type that use bearings to minimize friction. The rocker ratio of the modern engines is approximately from 1.5:1 to 1.8:1 which enables a boost in the lift of the camshaft. Enhanced fulcrum bearings are also integrated in high RPM engines for containment of stress as well as enhancement of durability to ensure that the Rocker Arm will efficiently perform in successive models of Pontiac Grand Prix.
