JXB Driveshaft Center Support Bearing Carrier Upgrade – BMW E3 E10 E12 E21 E23 E24 E28

Product Details

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.
