BMW Drivetrain Parts for BMW 3 Series G20 (2019+)

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.

Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Kit Includes: OEM Hengst Automatic transmission filter OEM Hengst Oil Pan Gasket & Installation Hardware OEM Hengst Drain plug with sealing washer OEM Hengst Fill plug with sealing washer 7 Liters of Liqui-Moly Top Tec 1800 ATF NOTE: Depending on the model, an additional liter of fluid may be necessary if you are draining your oil cooler or removing the valve body. As per ZF's recommendations, Turner Motorsport suggests performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle is modified and makes more power than stock or if your vehicle 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 like clutch packs and solenoids.

This kit Includes both of the front wheel bearing and hub assemblies plus Genuine BMW hardware. Wheel bearings can need replaced for a number of reasons, the most common being normal wear. If there is a loud humming, growling, or metal-to-metal noise while driving, it's likely that the bearing has failed. A simple way to check your bearing is to lift the wheel off the ground and try to move the tire back and forth by pushing the top and bottom of the tire in. If there is play, this commonly means the wheel bearing is worn out or has failed completely. The wheel hubs and bearings are already pressed together, simply bolt this new hub assembly to your front suspension carrier.
