The JXB driveshaft Carrier Upgrade is designed to replace the weak OEM centre bearing carrier on the driveshaft. The standard rubber construction allows too much movement under load, which can lead to driveline play, vibrations and misalignment of the driveshaft.
The JXB upgrade keeps the driveshaft firmly centred, resulting in more direct throttle response, tighter gear changes and better control under heavy load.
‘Street’ and ‘Track’ refer to the durometer (hardness) of the bushings. The Track bushings are approximately twice as hard as the Street bushings. Both Track and Street are many times stiffer than OEM and can handle heavy loads without any problems, but the Street bushings are better at absorbing driveline noise and vibrations.
In most cases, both Street and Track are completely silent and vibration-free. However, if there is an underlying problem in the drivetrain causing the drive shaft to vibrate heavily, the Track bushings may sometimes be unable to fully absorb this, whereas the Street bushings can.
We recommend Street bushings for any car not specifically built for track or off-road use, as Street bushings are less likely to transmit NVH (noise, vibration and harshness) into the cabin at high speeds or under heavy loads.
Not sure which to choose? Then the ‘Both’ option gives you a complete set of both Street and Track bushings. You can use all Street, all Track or even a combination of both to find the perfect balance between performance and comfort.

Frequently Asked Questions
What does a driveshaft carrier upgrade do?
It keeps the driveshaft better centred for more direct response and less play.
What is the difference between Street and Track bushings?
Street offers greater comfort, whilst Track is stiffer for maximum performance.
Does the driveshaft need to be removed?
No, installation is carried out without removing the driveshaft.
Does this increase NVH?
Street bushings minimise additional vibrations and noise.
