The Rocker Arm in Ford Explorer automobiles is an engine valvetrain component with a critical operation since it is responsible for moving the valve lift from the pushrod. Usually made from stamped steel or aluminum these parts translate pushrod lateral movement into the correct amount of downward force to open the valves. In high rotating speeds further aluminum is used due to lightweight whereas cast iron or forged carbon steel is used in diesel engines for higher strength. Both the standard and roller types of Rocker Arms have been used in Ford Explorer models with the automobile manufacturers offering a wide range of the Rocker Arm styles. Roller rockers that use needle bearings thus increases the power advantage when used in both the overhead valve and the overhead camshaft engines. The rocker ratio which is 1.5:1 to 1.8:1 in today's engines acts to amplify the lift of the camshaft leading to improved performance. Higher-performance fulcrum bearings are also employed where levels of stress and the required engine speed are high, for example in the Ford Explorer.
