Overview
The stock center support bearing carrier holds the driveshaft in place with rubber so thin about 20 lbs of force moves it from center to the end of its travel. While that's great for making sure no NVH makes it to the cabin, the stock bushing is extremely prone to failure, especially in harsher climates and on higher-powered cars. When the bushing lets go, it leads to excessive vibrations and clunking which can damage the transmission and rear diff. To make matters worse, the stock carrier is molded onto the non-serviceable center support bearing, leading to costly driveshaft replacement.
This upgraded unit keeps the driveshaft firmly in place at all times, and its polyurethane construction ensures it will never wear out. The thick bushings ensure the driveshaft cannot move from center, maintaining driveshaft alignment at all times.

Features & Benefits
✓
Eliminates Stock Bearing FailureThe stock rubber carrier is prone to failure in harsh climates and on higher-powered vehicles — this polyurethane upgrade solves the problem permanently.
✓
Locks Driveshaft On-CenterThick polyurethane bushings prevent the driveshaft from moving off-center, maintaining proper driveshaft alignment at all times.
✓
Protects Transmission & Rear DifferentialBy eliminating excessive vibration and clunking caused by bearing failure, this upgrade protects downstream drivetrain components from damage.
✓
Serviceable DesignUnlike the stock carrier which is molded onto the non-serviceable bearing and requires full driveshaft replacement when it fails, this upgraded carrier is built to last and can be serviced independently.
✓
Custom Isolator Bushing DesignAfter extensive design iterations, custom isolator bushings separate the carrier from the vehicle body and mounting hardware, substantially reducing NVH transmission into the cabin.
✓
Two Interchangeable Bushing OptionsStreet and track bushing options are both included and fully interchangeable, allowing you to tune the NVH vs. performance balance to suit your driving needs.
Frequently Asked Questions
Why does the stock center support bearing carrier fail so easily?
The stock carrier uses very thin rubber that only requires approximately 20 lbs of force to move the driveshaft from center to the end of its travel. While this reduces NVH, it makes the bushing extremely susceptible to wear and failure — particularly in harsh climates and in higher-powered applications.
What happens if I continue driving with a failed stock carrier?
A failed stock carrier allows the driveshaft to move off-center, causing excessive vibration and clunking. Over time this places abnormal stress on both the transmission and rear differential, potentially leading to expensive component damage.
Why is replacing the stock carrier so costly?
The stock carrier is molded directly onto the center support bearing, making the bearing non-serviceable. When the bushing fails, the entire driveshaft must be replaced rather than just the carrier — significantly increasing repair costs.
Which bushing option should I choose — street or track?
The street bushings absorb most drivetrain NVH and are recommended for daily-driven or street-focused vehicles. The track bushings offer no-compromise drivetrain rigidity but may produce substantial cabin noise. Both options are interchangeable, so you can try both and switch between them as needed.
Will the street bushings produce any noticeable NVH inside the cabin?
Some light NVH is possible at certain speeds in the form of a soft hum. In practice, with a modified exhaust or windows down, you'll likely never notice it.
