Performance and reliability receive enhancement through the implementation of the BMW M440i Rocker Arm component which functions in BMW M440i valve train assemblies. The Rocker Arm acts as a motion transmission device which distributes camshaft action to both intake and exhaust valves to manage ideal fuel and air mixture during combustion. Different M440i models can use stamped steel, roller tipped or full roller Rocker Arm designs for achieving customized performance benefits. Roller rockers operated by needle bearings deliver exceptional performance at high engine RPM because they reduce friction-related wear. The performance of the vehicle benefits from the efficient BMW M440i Rocker Arm which operates at a determined ratio between 1.5:1 to 1.8:1. The high-performance application requires upgraded fulcrum bearings to boost durability and reduce stress effectively. As a member of the BMW 4 Series family the BMW M440i defines itself through its 3.0-liter inline-six engine powered by TwinPower Turbo technology which produces strong horsepower and torque levels. A combination of performance components including the powertrain system and 8-speed automatic transmission as well as M Sport differential produces dynamic driving capabilities. The BMW M440i Rocker Arm elevates both performance and safety ratings while leading the automotive market through its superior engineering design and dependable features which has earned the automaker model its status as a leading model in driver-oriented vehicles.
