The Rocker Arm in Chrysler 300 vehicles is a very important component of the valvetrain system which enables the conversion of the motion of the pushrod to help open and close the intake and exhaust valves. Normally made of stamped steel or aluminium, rocking the Rocker Arm has to swing in the required vertically upwards to produce the downward movement necessary to open the valves. When requirement of high RPM is there, aluminum is used for lighter weight, for diesel engines, cast iron or forged carbon steel is used. The Chrysler 300 ROCKER ARMS may consist of conventional and roller Rocker arms. Roller rockers, which utilizes needle bearings provide low friction and wear as compared to other conventional rocker which operates on metal on metal mode. Typically, ranked rocker in these engines varies between 1,5 to 1,8 thus under the camshaft lift is boosted. Another application of improved fulcrum bearings is in the Chrysler 300 engines under conditions of high RPM to address the pressure issue and subsequently, the prospects of the part's decay.
