Rocker Arm utilized in Jeep Wrangler cars plays a crucial part in the valvetrain mechanism of the internal combustion engine whereby it help to transmit motion from the pushrod to the intake and exhaust valves. Usually made of stamped steel or aluminum, the Rocker Arm is designed that the movement of a pushrod in the vertical plane corresponds to the required reciprocating movement to activate the valves. For high RPM applications aluminum is the favored metal due to light weight while cast iron or forged carbon steel is engaged in diesel motors for sturdiness. There are variations of the Rocker Arms including the roller rockers gadget that uses the bearings to minimize on friction hence enhancing efficiency in comparison to another Rocker Arms gadget. The rocker ratio, which has been between 1.5:1 and 1.8:1 in the contemporary engines, enables greater amounts of camshaft lift enhancing the performance. Higher usage fulcrum bearings are also used in high RPM Jeep wrangler vehicles to handle stress as well as to enhance the longevity of a Rocker Arm in these models.
