BMW Drivetrain Parts for BMW E60 M5 S85 5.0L

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.

As components in the differential begin to wear, metal particles become loose in the diff fluid, which can lead to excess wear. This magnetic plug pulls these particles out of suspension, helping to reduce wear over time. Replaces BMW # 33117525064

This bushing is the point where the shifter arm pivots. If you are experiencing excess play in your shifter, this could be the cause. Worn out shifter ball bushings allow too much movement from wear over time.

Although some regarded the SMG as a "revolutionary" transmission system, it came with its own set of issues. One of the most common solutions for addressing an aging SMG system is converting it to a manual transmission. Manual transmissions are not only easier to maintain but also provide a more engaging driving experience and offer a broader range of upgrade options compared to the SMG system. This kit includes the essential components needed to replace your SMG transmission with the GDS6-53BZ 6-speed transmission (sold separately) from the E90 M3. See the kit contents tab for a full breakdown of the included components.
