BMW Drivetrain Parts for BMW 5 Series E34 (1987-1995)

Clear BMW chassis

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.

Looking to upgrade your stock clutch to something a little more beefy? The performance clutch kits from DKM are a great option to help get power to the wheels without breaking the bank.

Pressure Plate
Sprung Organic Disc
Iron Single Mass Flywheel
Pilot Bearing/Bushing and Throw-out Bearing

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.
