The Rocker Arm is one of the important engine components that is used in valvetrain system for Chevrolet Suburban cars and its functions lies in the conversion of motion from the pushrod to the intake and exhaust valves. Usually made from stamped steel or aluminum, these parts actuate to translate vertical movement of the pushrod to the kind of lifting force needed to open the valves. Aluminum is used in reciprocating engines where the engine RPM is very high because of the strength to weight ratio Aluminum is nearly six times lighter than cast iron However, cast iron or forged carbon steel is used in diesel engines to make them very strong. There has been the use of a number of rocker arm designs including the standard and the roller rocker arm. Roller rockers, which have low friction, so cushioned by needle bearings, are easier to fit in overhead valve and overhead camshaft engines. The rocker ratio that is typical with the Chevrolet Suburban engines is between 1.5:1 and 1.8:1 which provides boosted lift courtesy of the camshaft. Greater fulcrum bearings are also found in high RPM engines for handling of stress as well as durability.
