JXB Performance Driveshaft Center Support Bearing Carrier Upgrade

The stock center support bearing carrier holds the driveshaft in place with a layer of thin rubber. While that’s great for making sure no NVH makes it to the cabin, it doesn’t keep the bearing centered well under load, allows the bearing to sag and ruin driveshaft alignment over time, and creates slop in the driveline during shifts and throttle application.

Over time the OEM bushing becomes brittle, eventually dry rotting and cracking. Even on the best-kept cars, the stock bushing can start to form cracks in as little as 5-10 years.

When the bushing wears and sags, it changes the alignment of the driveshaft, putting more stress on the joints. During rapid loading of the driveshaft (launches, shifts, and quick application of the throttle), the bearing is allowed to travel off-center, introducing slack in the driveline, which results in laggy and unpredictable driveline response.

The JXB upgraded driveshaft carriers keep the driveshaft firmly in place at all times. The more solid bushings ensure the bearing cannot move from center, maintaining torque delivery and driveshaft alignment at all times, resulting in more direct driveline response under all conditions.

Difference between Street and Track

Street and Track refer to the stiffness of the bushings.

• Track bushings have about twice the hardness of street bushes. Both track and street bushes are many times stiffer than the original bushes and can withstand any load.
• Street bushings however, are better able to absorb drivetrain noise and vibration. Normally, both road and track bushings are completely silent and vibration free, but in cases where there is a problem with the drivetrain that causes severe driveshaft vibration, the track bushings may not be able to absorb it all while the road bushings can.

In general, we recommend street bushings for all vehicles that are not specifically built for use on the racetrack or off-road, as the bushings are much less likely to transmit noise and vibrations to the interior at high speeds or under heavy acceleration.

If you're not sure which bushings to choose, the "Give me both" option gives you a complete set of bushings for both road and track use. You can use all the bushes for road or track use or even mix them to find the perfect balance between performance and damping characteristics.
