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.

Drive axle seal, located on the front differential. This seal works on both the left & right side axles. Due to regular exposure to dirt and debris, axle seals are a common failure item. An axle seal failure can cause fluid to leak from the differential housing, eventually causing it to run dry, which can result in front differential failure. Prevent a dangerous failure and costly repair bill by replacing your compromised axle seals with this genuine component directly from BMW. Replaces BMW p/n 31508860349, 31508743675, & 33107505601
