BMW Drivetrain Parts for BMW 3 Series F30 (2012+)

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.

A common source of leaks, the selector shaft seal should be replaced whenever the shifter assembly is serviced to prevent fluid loss.

Fits the following BMW chassis:

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.

Eliminate the factory clutch delay valve and enjoy faster, more precise clutch engagement with the ECS Clutch Delay Valve (CDV) Removal Tool Kit. Designed for F and G-Chassis manual BMWs, this kit makes removing the hydraulic restrictor safe, simple, and reliable, no slave cylinder removal required.

Most modern BMWs come from the factory with a plastic slave cylinder featuring a CDV, intended to smooth engagement and reduce driveline shock for less experienced drivers. In practice, this restrictor can dull pedal feedback, slow shifts, and increase clutch wear. Removing it restores the sharp, direct clutch feel that BMW enthusiasts expect.

Key Benefits:

Faster, more predictable clutch engagement
Sharper pedal response and connected driving feel
No need to remove the slave cylinder
Tool Design:

Machined from durable 304 stainless steel
Includes precision removal and insertion tools
Knurled grip for easy handling
Built-in depth and angle control protects internal surfaces and ensures proper grommet alignment
Removal and Installation:

Disconnect the Clutch Line
Remove the clutch line from the slave cylinder to access the factory clutch delay valve.
Remove the Restrictor Plate
Thread the removal tool into the center of the small grommet. Once engaged, carefully pull the tool to remove the grommet and restrictor plate. The small rubber sealing O-ring will come out along with the plate.
Reinstall the O-Ring
Place the rubber O-ring onto the installation tool. Insert the tool into the slave cylinder to properly seat the O-ring in its original position.
Reconnect and Bleed the Clutch
Reattach the clutch line, add fluid, and bleed the system according to your manufacturer’s instructions.
Enjoy Enhanced Clutch Feel
With the delay valve removed, your clutch now engages faster and more predictably, giving your manual transmission the sharp, connected feel it was designed for.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components.
