The stock center support bearing carrier is engineered to minimize noise, vibration, and harshness (NVH) in the cabin by loosely securing the center bearing with a soft rubber bushing. However, this design allows the driveshaft to move off-center during launches and shifts, reducing throttle response and causing drivetrain oscillations. Over time, the rubber bushing can sag or dry rot, leading to misalignment of the driveshaft.
Prevent or fix this common problem with JXB Performance's Driveshaft Center Support Bearing Upgrade! This upgrade features a simple yet highly effective 2-piece design that makes installation and bushing replacement effortless. The stock carrier is cut away, and the JXB bushings securely "clamp" the driveshaft bearing in place, ensuring constant driveshaft alignment.
The Street bushing option from JXB is the most popular choice, offering a significant improvement over the stock design while keeping NVH levels minimal.
Note: Some light NVH, such as a soft hum, may occur at certain speeds. However, with a modified exhaust or open windows, it’s unlikely to be noticeable.
Installation is straightforward and doesn’t require removing the driveshaft. The 2-piece design clamps directly onto the OEM bearing, though removing the old carrier will require a cutting tool.

The ECS Tuning Center Support Bearing Brace is engineered to improve drivetrain performance and longevity. The factory center support bearing features internal an internal rubber bushing to reduce NVH (noise, vibration, and harshness) transmission to the cabin. Unfortunately, this material choice falls short when it comes to performance applications. Under extreme load conditions, this bushing is prone to flexing, resulting in driveshaft misalignment. To address the shortcomings of the factory rubber center support carrier design, ECS engineers developed a set of precision-fit, split polyurethane bushings that secure tightly around the existing driveshaft bearing. Constructed from 90A durometer polyurethane, this material eliminates bushing deflection while maintaining minimal noise, vibration, and harshness (NVH). By eliminating deflection, this innovative solution not only improves durability but also ensures a significantly longer service life than the OEM center support bearing—making it an excellent upgrade for aging BMW chassis.
The polyurethane bushings are surrounded by a robust 6061-T6 billet aluminum bracket designed with strength and reliability in-mind. This bracket features a split design for hassle-free installation, eliminating the need to remove the driveshaft assembly entirely. To install the ECS Center Support Carrier, simply cut around your existing bearing, remove the factory brace, and clamp on your new bushings and bracket. This user-friendly approach saves time and simplifies maintenance or upgrades. Two stainless steel socket head screws are used to fasten the two-piece bracket, offering corrosion resistance and secure clamping under high torque and stress. This combination of materials and design ensures dependable performance and long-lasting durability, even in demanding applications.

Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.
