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. Custom isolator bushings separate the carrier from the body of the vehicle and mounting hardware to substantially reduce NVH levels compared to typical aftermarket solutions.

Frequently Asked Questions
Which bushing option should I choose?
Street bushings are ideal for daily driving with minimal NVH, while track bushings offer maximum performance. If unsure, choose both options as they're interchangeable.
How much NVH will I experience with street bushings?
Street bushings absorb most drivetrain NVH. Some light humming at certain speeds is possible, but with modified exhaust or windows down you'll probably never hear it.
Can I swap between street and track bushings later?
Yes, the bushings are completely interchangeable, allowing you to change between configurations as needed.
Why does the stock carrier fail?
The stock rubber bushing is extremely thin and prone to failure in harsh climates and high-power applications. It's also molded to the bearing, requiring full driveshaft replacement when it fails.
What damage can a failed stock carrier cause?
When the stock bushing fails, it creates excessive vibrations and clunking that can damage both the transmission and rear differential over time.
