The Rocker Arm in Lincoln Navigator automobiles is an extremely critical component of the internal combustion engine's valvetrain system since it acts as a medium through which the mechanical movement coming from the pushrod is translated into a recognizable motion for both the intake and the exhaust valves. Usually made from stamped steel or aluminum, the Rocker Arm translates the back-and-forth percussive movement of the pushrod into the kindof pushing force needed to open the valves. Aluminium is used in high-RPM applications for its lightweight characteristics while cast iron or forged carbon steel is used in the form of diesel engines. Different types of Rocker Arms, for instance, roller rockers, utilize needle bearings in order to decrease friction and use which increases the efficiency of the unit as compared to its counterparts. The Rocker Arm of the Lincoln Navigator usually has a rocker ratio of between 1.5:1 to 1.8:1 because this increase the camshaft lift and thus the performance of the engine. There are also enhanced fulcrum bearings used in stress and durability of high RPM engines thus the Lincoln Navigator performance is optimal.
