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.

The stock center support bearing carrier is designed to reduce NVH to the cabin by loosely holding the center bearing with a flimsy rubber bushing. During launches and shifts, the driveshaft is allowed to travel off-center, decreasing throttle response and causing oscillations through the drivetrain. As they age, the carrier rubber sags and dry rots, ruining the driveshaft alignment. Fix or prevent this common issue with JXB Performance's Driveshaft Center Support Bearing Upgrade! JXB utilizes a simple but extremely effective 2-piece design which allows you to install this upgrade and replace bushings with ease. The stock center support carrier is simply cut away, allowing the JXB bushings to "clamp" down on the driveshaft bearing and hold the driveshaft securely in place, maintaining driveshaft alignment at all times. Two bushing options are available for this kit, Street and Track, both of which are many times better than the stock bushings: The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. (With a modified exhaust or windows down, you’ll probably never hear it) The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? Try them both, they’re interchangeable! Installation does not require the removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. Looking for replacement or additional bushings? See T#4799658 for replacement street bushings and T#4799659 for replacement track bushings.

The stock center support bearing carrier utilizes an extremely thin layer of rubber to secure the driveshaft, allowing for minimal movement to effectively insulate the cabin from noise, vibration, and harshness (NVH). However, this design is less effective at maintaining proper bearing alignment under heavy loads. Over time, it allows the bearing to gradually sag, disrupting the driveshaft alignment and introducing play in the driveline during gear shifts and throttle application. The original equipment manufacturer (OEM) rubber bushing has a tendency to sag, become brittle, and eventually deteriorate, resulting in dry rot and cracking. Even in well-maintained vehicles, the stock bushing can develop cracks in as little as 5-10 years. When the bushing loses its integrity, it can lead to pronounced vibrations, clunking noises, and increased stress on the bearing. Adding to the challenge, the stock carrier is permanently molded onto the center support bearing, making replacement a difficult task that typically necessitates specialized tools.
