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.

The BMW F10/F07 Rear Diff Rear Mount Bushing by Powerflex is a specialized upgrade designed to replace the OEM rubber bushings in the rear differential mount. Here's a breakdown of its key features and benefits:

  1. Durability and Longevity: Made from high-quality polyurethane, these bushings are significantly more resistant to wear compared to the stock rubber, which tends to degrade over time due to heat, oils, and mechanical stress.

  2. Enhanced Performance: The stiffer material reduces flex in the rear differential, ensuring more precise power transfer to the wheels. This results in better acceleration response, reduced wheel hop, and improved handling characteristics, especially during aggressive driving.

  3. Reduced Differential Movement: The stock bushings can allow excessive differential movement under load, leading to a less stable rear end. The Powerflex bushings minimize this movement, enhancing the overall driving dynamics.

  4. Balanced Comfort and Performance: While polyurethane bushings are firmer than rubber, Powerflex designs their bushings to maintain a balance between performance and comfort. This means less increase in vibration, noise, and harshness (NVH) compared to other aftermarket bushings, making them suitable for both daily driving and performance applications.

  5. Custom Fit for BMW F10/F07: Specifically engineered for the BMW 5 Series (F10) and BMW 5 Series GT (F07), these bushings offer a precise fit, ensuring easy installation and compatibility with factory components.

Overall, the Powerflex Rear Diff Rear Mount Bushing is a go-to upgrade for those looking to improve their BMW’s rear-end stability, responsiveness, and durability without sacrificing too much comfort.

The BMW F10/F07 Rear Diff Front Mount Bushing from Powerflex is a performance-enhancing replacement part designed for the rear differential mounting system. Here are its main features: Polyurethane Construction for Longevity: Made from high-quality polyurethane, these bushings outperform traditional rubber bushings by resisting wear from heat, oils, and road contaminants. This means they provide a longer service life, reducing the need for frequent replacements. Enhanced Power Transfer: By limiting excess differential movement, the stiffer Powerflex bushings allow more precise power transfer to the rear wheels. This results in sharper throttle response and improved overall drivetrain efficiency, especially during spirited driving. Increased Rear-End Rigidity: The factory rubber bushings allow for some differential movement, which can lead to instability. The Powerflex bushings reduce this flex, resulting in a more stable and predictable rear end, particularly when cornering or under heavy acceleration. Improved Handling and Stability: With reduced play in the differential mounting points, the rear suspension geometry stays more consistent. This translates to sharper handling, better grip in corners, and a more connected driving experience, making the vehicle feel more composed. Controlled NVH (Noise, Vibration, and Harshness): Powerflex engineers their bushings to strike a balance between performance and comfort. While polyurethane is stiffer than rubber, these bushings are designed to minimize the increase in NVH, ensuring that the ride remains comfortable for daily driving while still benefiting from enhanced performance. Direct Fitment for BMW F10/F07: These bushings are specifically designed for the BMW 5 Series (F10) and BMW 5 Series GT (F07), providing an easy, direct replacement for the original equipment. This ensures compatibility and smooth installation.
