The Rocker Arm found in Chevrolet Astro cars has a very crucial role to play in the motion of the valves in the internal combustion engines whereby the Rocker Arm translates the motion of the pushrod to the intake and exhaust valves. Most commonly made from stamped steel or aluminum, the Rocker Arm is a lever that translates the movement of the pushrod, in the vertical direction, into the amount and direction of force required to open the valves. Aluminum is preferred for building engines of high RPM because of its lightweight, whereas cast iron or forged carbon steel is incorporated in diesel engines due to durability. Hence, different Chevrolet Astro models can have two standard types Roocker Arms and the additional type- roller rockers. Roller rockers, mounted with needle bearings, have less friction and wearing ability than metal to metal ones having better performance. The rocker ratio in these engines normally varies between 1.5 to 1:1- 1.8 to 1 for increasing also the camshaft lift which in turn improves the efficiency of the engines. Other improvements that are often seen in these engines include replaced fulcrum bearings especially in engines with a high RPM requirement in Chevrolet Astro.
