BMW Drivetrain Parts for BMW X5 M S63 4.4L

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Engineered to maintain strict driveline alignment, this Meyle Drive Shaft Center Support Bearing mitigates harmonic resonance and rotational deflection across two-piece driveshaft assemblies. Constructed with an OE-grade vulcanized rubber cushion and a high-load-capacity, pre-greased ball bearing, it effectively isolates the chassis from drivetrain NVH (Noise, Vibration, and Harshness). Installing this precision-manufactured component ensures optimal torsional stability, reducing premature fatigue on adjacent universal joints and transmission output seals.
