The stock center support bearing carrier is permanently molded to the center bearing with thin rubber that sags and cracks over time and does not adequately support the driveshaft under load. This rubber generally fails long before the bearing itself has reached the end of its life. Since the center bearing is molded to the OEM carrier and difficult to service, it’s often easier to get a new driveshaft than replace the center support bearing.

The first video below was recorded on an Audi, and the 2nd on a BMW, but Chrysler (and everyone else’s) OEM carrier design is similar. The shaft is not well-supported by the soft OEM carrier, so it’s allowed to travel off-center during rapid loading and unloading. The second video shows a comparison of how much an OEM carrier gives under load and the improvement with the JXB carrier.

This upgraded unit keeps the driveshaft firmly in place at all times, and its robust construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times. The 2-piece design clamps around the bearing, making installation and servicing a breeze.

Two options are available for the bushings, both of which are many times over better than the stock bushing. We’ve paid close attention to the NVH levels associated with this upgrade. After extensive design iterations, we’ve come up with custom isolator bushings that separate the carrier from the body of the vehicle and mounting hardware. These carriers substantially reduce NVH levels.

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? They’re interchangeable so you can try them both.
