BMW Drivetrain Parts for BMW X6 M S63 4.4L

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.

Located between the transmission and driveshaft, the giubo (also guibo) joint is a flexible rubber drive coupling that joins driveline components to reduce vibration, while allowing a limited range of flexibility. Joint rubber deteriorates over time from torque stress and heat hardening. A failed joint is a common cause of driveline noise and vibration. ​This kit from Febi includes all of the basic components needed to install the flex disc.

Responsible for transferring power from the transfer case to the front differential, the front driveshaft experiences wear and tear over time, leading to play in its universal joints. This wear often results in a noticeable driveline vibration at higher speeds.

As the universal joints are non-serviceable components, replacing the entire driveshaft assembly is the recommended solution. Febi-Bilstein provides a cost-effective and high-quality reproduction unit designed to meet your performance needs.

For a durable and reliable repair of your front driveshaft, opt for Febi-Bilstein to ensure lasting results.

Rein OE Transfer Case Overhaul Kit is a solution kit developed to perform a complete overhaul of the xDrive transfer case. The complete kit includes bearings, clutch packs, shims, magnets, retainers, hardware, seals, and other necessary internal components. Until now, the only solution to repair these failure-prone transfer cases was to replace them with a complete assembly at the dealer or install a used assembly at the local shop. No other options were available due to no offering for internal components. All the components offered in Rein's Transfer Case Overhaul Kit are OE, identical to the original parts on the vehicle direct from the factory. Features: Includes all OE components Solution for T-cases that were damaged from overheating or lack of service made to strict OE engineering quality standards 4 year/50,000 mile warranty The kit was designed to service the ATC 45L transfer cases found in the F85 & F86 models as BMW part numbers 27107854164 and 27105A371E4

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.
