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 allows the bearing to sag and ruin driveshaft alignment over time.

Over time the OEM bushing becomes brittle, eventually dry rotting and cracking. On many F150 models the carrier is unserviceable, leading to complete driveshaft replacement as the only option.

Our upgraded driveshaft carriers allow you to service the center support by clamping around the original bearing. The more solid bushings ensure the bearing cannot move from center, maintaining torque delivery and driveshaft alignment at all times.

Our unique shoulder bolt and damper bushing method for securing the carrier to the frame reduces vibration transfer to the cabin and allows the carrier frame to move forward and backward with the bearing, preventing the type of failure shown in the last photo.

The videos below were recorded on a 2020 Explorer ST with just a tune. The driveshaft is not well-supported by the soft OEM carrier, so it’s allowed to travel off-center under load. The video shows a comparison of how much an OEM carrier gives under load and the improvement with the JXB carrier.

Installation doesn’t require removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required.

The exact steps to access the carrier will vary slightly by model, but the removal and installation of the new carrier are the same. The basic steps are:

• Cut off OEM carrier and remove rubber support material with razorblade, leaving base layer of rubber intact on the bearing

• Clamp new carrier around OEM bearing

• Most Ford F150 2004-present with 2-pc driveshaft and center support bearing

  • Generally shorter to mid length wheelbase trucks may have come with a 1-pc driveshaft from the factory

  • 4x4 trucks are more likely to have a 1-pc driveshaft from the factory

• Does not fit 2021+ Hybrid models or 3.5T 4x4 with 157/164” wheelbase

• If you’re unsure if your truck has a center support bearing, please look under your truck and confirm before ordering. The center support bearing is easy to see.

• Trucks with rear lift kits require the center support bearing spacer kit to correct pinion angles.

Street and Track refer to the durometer (stiffness) of the bushings. Track are roughly twice the durometer of the street bushings. Both track and street will hold up to whatever abuse are thrown at them, but the street bushings are better at soaking up drivetrain noise and vibration. Usually both street and track are completely silent and vibration-free, but in cases where there is an underlying drivetrain issue causing the driveshaft to vibrate badly, the track bushings may not be able to soak it all up, where the street bushings can.

We generally recommend street bushings for any car that's not purpose-built for track or overland use, since the street bushings have a much lower chance of transmitting drivetrain NVH to the cabin at high speeds or under heavy throttle loads.

If you’re not sure which to go with, the “Give me Both!” option will give you a full set of each of the street and track bushings. You can use all street, all track, or even mix and match them to find the perfect balance of performance and NVH-absorption.
