Ford Expedition has a Rocker Arm that has a significant performance in the valvetrain system, it helps the pushrod translate the motion into the operation of the intake and exhaust valves. Usually made from stamped steel or aluminum, the Rocker Arm has the responsibility of changing the vertical motion of pushrods into the required pressure needed to pull the valves open. High rpm requires lightweight metals, thus aluminium while for low rpm engines such as diesel engines, cast iron or forged carbon steel are used due to their strength. Different types of Rocker Arms that exist in the current market for instance roller rockers comprise of needle bearings that eliminate friction therefore enhancing the performance of the unit. The rocker ratio of the new Ford Expedition engines varies between 1.5:1 and 1.8:1, thus, camshaft lift is increased to enhance performance. Other enhancements that are used in the fulcrum bearings include the upgraded bearings to deal with pressure in high-RPM engines and improve the general Rocker Arm system strength.
