BMW Drivetrain Parts for BMW 8 Series E31 (1991-1997)

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.

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

Transmission fluid is responsible for both cooling and lubricating sensitive transmission components. Over time, this fluid becomes contaminated by particulate from clutch and gear components wearing down. This contamination reduces the fluid's ability to act as a lubricant, eventually leading to increased wear and tear within the transmission. To prevent excess wear and keep your transmission in top shape, the fluid and filter should be replaced regularly. As per ZF's recommendations, we suggest performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle has been modified to produce more power than stock or if it is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination, which will help extend the life of internal transmission components, such as clutch packs and solenoids.

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This filter fits A5S440Z automatic transmissions on BMW E39 540I E38 740I 740IL E31 840I 840CI E53 X5 4.4I 4.6IS

Wheel bearings can need replaced for a number of different reasons. On some vehicles, when removing the front axles, it is required that you also replace the wheel bearings before reinstallation. If the wheel turns with a gritty feel or there is a loud metal to metal noise when on the road, your bearings have failed. Wheel bearings on modern vehicles usually need pressed in. If that is the case with your vehicle, specialized tools such as a shop press may be needed to install this bearing. Check what is required to do your wheel bearing prior to ordering.
