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.

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. 

Engineered to perform, Powerflex performance polyurethane differential bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

NOTE: We suggest replacing 3 of BMW # 31126760203 during installation Kit comes supplied with M14 mounting bolt, thread locker, and a Powerflex keyring. With the newer F8x M2/M3/M4's making big power and having superb chassis straight from the showroom, it's no wonder they're often found at the most serious of track-days or at tuning shops around the globe. Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicles' suspension components- most notably the rear differential bushings. Despite having alloted for two mounting bushings on the factory tubular subframe, BMW opts to use only a single offset bushing in the rear to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn out and softer than they once were. With hard launches and sudden and frequent on-off throttle changes, the single rear OE rubber bushing is subject to extreme torsional and directional forces, resulting in rapid degradation with failure often seen at around the 30,000-40,000 mile mark, and an unsettled and potentially clunky rear-end. The PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminum, and is designed to utilize the secondary mounting position on the OE subframe. With the addition of a second bushing, this prevents the diff from twisting under load, providing benefits such as: Reduced drivetrain movement Improved throttle response A more controlled and consistent chassis response to acceleration/deceleration Improved tire-to-road power transfer due to reduced wheel hop Reduced strain on bushings The corrosion-resistant, satin black, anodized aluminum bracket is optimized for high stress and deflection while withstanding high torque loads, but serves the same purpose in road-use and track-use cars with either a single OE bushing or dual aftermarket bushings. Although the bracket can be fitted without the need to remove the subframe from the vehicle completely, we would strongly recommend combining Powerflex products by using our already hugely popular 80A durometer PFR5-4026 Rear Diff Rear Mounting Bushings for both rear mounting positions alongside our PFR5-4025 Rear Diff Front Mounting Bushings in the front for the ultimate in differential control and a lasting street or track solution.

The Powerflex BMW E34 5 Series / E32 7 Series Rear Diff Rear Mount Bushing is designed to enhance the performance and durability of the rear differential mounting system in BMW models. By replacing the factory rubber bushing with high-performance polyurethane, this bushing provides improved handling and longer-lasting reliability.

Key Features:

  • Precision Fit for E34 and E32 Models: Engineered specifically for the BMW E34 5 Series and E32 7 Series, this bushing is a direct replacement for the rear differential’s rear mount. It ensures a secure fit, keeping the differential properly aligned for optimal performance.
  • Polyurethane Durability: The bushing is made from tough polyurethane, which offers superior resistance to wear and degradation compared to the factory rubber bushings. This material is designed to withstand extreme conditions, such as heat, oil exposure, and road contaminants, ensuring it remains effective for much longer.
  • Enhanced Drivetrain Control: Replacing the softer rubber bushing with this firmer polyurethane bushing reduces differential movement under load, resulting in better power transfer and more precise handling. It minimizes drivetrain slop, making the vehicle feel more responsive during acceleration and cornering.
  • Improved Handling Performance: By limiting excess movement in the differential, the bushing enhances rear-end stability and helps maintain better control of the vehicle. This leads to sharper, more predictable handling, especially when driving aggressively or under heavy load.
  • Maintained Comfort: While this bushing improves performance, it is also designed to retain a degree of ride comfort. The material strikes a balance between firmness for improved handling and flexibility for everyday drivability, making it suitable for both spirited driving and regular use.

This Rear Diff Rear Mount Bushing is perfect for BMW E34 and E32 owners looking to improve their vehicle’s rear suspension dynamics and drivetrain stability. It’s an ideal choice for enthusiasts who want better control and responsiveness without sacrificing too much ride comfort, offering a long-lasting, low-maintenance upgrade for daily driving or performance use.

Differentials serve the key purpose of transmitting power from the driveshaft to the axles. Factory rubber bushings absorb some of this power to allow for cushy, comfortable acceleration, at the expense of performance. Many OEM differential bushings are fast-wearing and failure prone, resulting in driveline slop and thunks when shifting or going over bumps. Powerflex polyurethane differential bushings are firmer than OEM rubber bushings, eliminating associated driveline slop and allowing for the crisp application of power to the ground, resulting in better throttle response and control. Powerflex is the number one selling suspension bushing manufacturer in Europe. Their experience with polyurethane bushing material and state-of-the art manufacturing techniques allows them to produce premium performance bushings, made to exact-fit standards. Powerflex performance polyurethane bushings are built to last longer than OEM rubber bushings, while improving performance and allowing for a more engaging driving experience. Use of Powerflex Copper Grease PCG1 is recommended for ease of installation. Periodic reapplication is recommended to extend squeak-free service life of bushings. Powerflex Black Series bushings are the ultimate in track and race bushings. Need bushings for a car that's street-driven? Powerflex street bushings are an ideal alternative for street driven vehicles and those that see occasional autocross or track time. Powerflex is proud to offer a lifetime warranty to the original purchaser on all products.

Poly bushings give a provide a more connected feel between you and your vehicle via a higher durometer than stock rubber bushings. Sometimes, this can be at the expense of NVH (noise, vibration, and harshness), but if you are driving your car on the track or just commuting in a spirited manner, poly may be a good option for you!

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. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.
