The BMW M550i xDrive Rocker Arm is the magnificent component that positively influences the performance and durability of the BMW M550i xDrive models. This Rocker Arm is designed to functionally transfer motion between the pushrod and the intake and exhaust valves thus making it easier for the engine to run. Usually made of lightweight materials, such as an aluminum or stamped steel, the Rocker Arm is able to impart the required force of the vertical direction to open the valves and increase engine efficiency. Roller rockers with needle bearings reduce the friction and wear, and that is important for achieving and sustaining the high level of performance which is characteristic to BMW M550i xDrive. Because of the rocker ratio, the Rocker Arm has 1.5:1 to 1.8:1 that increase camshaft lift; in the M550i xDrive model, coupled with the twin-turbo 4.4-liter V8 engine, the result is 523 horsepower and 553 lb-ft of torque. This performance is further supported by improved fulcrum bearings to guarantee sturdiness even when working at high revs, thus improving on reliability as well as safety. This Rocker Arm is well designed and functions well with different versions of the M550i xDrive and thus has enhanced its market position in the automotive industry. Additional nuances like the compatibility with high technologies like the brand's iDrive 7.0 make the M550i xDrive even more unique and exceptional, which, in turn, should attract those who look for a combination of comfort and sportiness.
