JXB Performance Ford S197 Mustang Driveshaft Center Support Bearing Carrier Upgrade (Mustang GT 2005-2014)

The stock center support bearing carrier holds the driveshaft in place with layers of thin rubber connected by small ribs that sag over time. 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.

Our 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.

Benefits as described by our customers include:

• More direct throttle response

• Firmer, more direct shifts

• More instantaneous launches

• Reduction in vibration due to driveshaft misalignment and/or rubber deterioration

• Smoother low-speed on/off throttle behavior (1st gear in parking lots)
