JXB Repair Kit for the JXB Driveshaft Centre Support Bearing of Chrysler 300C, Dodge Challenger and Charger from 2015 to 2023

The standard centre bearing carrier holds the driveshaft in place with a thin layer of rubber. While this is great for ensuring that no annoying noise gets into the cabin, it does not keep the bearing well centred under load, allows the bearing to sag, deteriorates the alignment of the driveshaft over time and causes shocks in the drivetrain when shifting and accelerating.

Over time, the OEM bushing becomes brittle and can eventually become brittle and crack. Even in perfectly maintained cars, the original bushing can crack after just 5-10 years.

If the bushing wears and gives way, it changes the alignment of the drive shaft and puts more stress on the joints. If the drive shaft is loaded quickly (starts, gear changes and rapid acceleration), the bearing can run off-centre, causing the drivetrain to sag, resulting in a delayed and unpredictable response from the drivetrain.

This improved driveshaft carrier from JXB keeps the driveshaft firmly in place at all times. The more solid bushings ensure that the bearing cannot get off centre, ensuring torque delivery and driveshaft alignment at all times, resulting in a more direct drivetrain response in all conditions.

• Reduces the sagging of the drivetrain
• Restores and maintains the alignment of the drive shaft
• Assembly without removing or dismantling the drive shaft
• Fits all Charger/Challenger/300 from 2015 to 2023
• Fits RWD and AWD
• Fits V6 and V8
• Fits automatic and manual transmissions

The advantages of the JXB repair kit described by our customers include

• More direct response of the accelerator pedal
• Tighter, more direct gear changes
• More direct acceleration
• Reduced vibrations due to misalignment of the drive shaft and/or rubber wear
• Smoother behaviour when changing loads at low speeds (1st gear in car parks)

Difference between Street and Track

Street and Track refer to the stiffness of the bushings.

• Track sockets 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 sockets 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.
