The Rocker Arm can be optimal described as an important component of the engine's valvetrain in Ram 3500 vehicles and it has the significant function of transmitting the motion of the pushrod to the valves' intake and exhaust. Usually made of stamped steel or aluminum, the Rocker Arm relays the up and down shake of the pushrod into the amount of force that will sufficiently open up the valves. Generally in high RPM, Aluminum is used due to its light weight while cast iron or forged carbon steel is used in diesels. Different types of Rocker Arm have been used in the Ram 3500 models, there are the standard ones and roller types of Rocker Arm. Roller rockers are desirable in the overhead valve engines equipped with needle bearings to enable low friction, like in overhead camshaft engines. The rocker ratio varies from 1.5:1 to 1.8:1 in most of the modern engines and by using this element the toughness of the camshaft lift intensifies. Other upgraded fulcrum bearings are also found in high RPM range where stress and durability of the Rocker Arm in Ram 3500 vehicles are imperative.
