BMW Drivetrain Parts for BMW X5 M S63 4.4L

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.

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
