Rein BMW Drivetrain Parts for BMW X Series F15 (2014+)

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.

The Rein OE Transfer Case Overhaul Kit is a solution kit developed to perform a complete overhaul of the X-Drive transfer case. The kit is comprised of the sprocket, shims, clutch pack, chain, gears, and other necessary internal components. Until now, the only solution to repair these failure prone transfer cases was to replace with a complete assembly at the dealer or install a used assembly at the local shop. No other options were available due to no offerings for internal components. This kit specifically caters to the chain drive portion of the ATC 45L transfer case. 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.
