In the Dodge Ram 1500 car models, the Rocker Arm plays a significant part in the engine's valvetrain mechanism, its main function is to transfer the motion from the pushrod to the intake and exhaust valves. Usually made of stamped steel or aluminum with a strong solid design, the Rocker Arm move vertically through the push rod push and change it into the required amount of force to actuate the valves. Aluminum is used for its lightweight characteristics particularly in high-RPM operations while cast iron or forged carbon steel is employed in diesel operations due to their robustness. Some of the Rocker Arms which may be found in Dodge Ram 1500 models are the standard and the roller rockers. Roller rockers which do not require use of bearings to lessen friction are appropriate for the overhead valve as well as the overhead camshaft engines. The rocker ratio which for modern engines is between 1.5: 1 and 1.8: 1 can increase camshaft lift and hence enhance the performance of the engine. Higher revving engines of the Dodge Ram 1500 also feature upgraded fulcrum bearings to deal with the stress and to provide extra strength.
