Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.
Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.
Features & Benefits:
Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:
Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:
Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

The Powerflex Black Series Rear Diff Front Mount Insert for the BMW F22 (2 Series), F30 (3 Series), and F32 (4 Series) is a robust and high-performance bushing designed for motorsport and aggressive driving. It's part of Powerflex’s Black Series line, which prioritizes precision and control by using a stiffer polyurethane material to enhance the vehicle's dynamics.
Material and Hardness: Made from 95A durometer polyurethane, the Black Series is much firmer than standard bushings, designed specifically for track use. This stiff material drastically reduces unwanted movement in the differential mount.
Enhanced Driving Precision: By reducing flex in the front differential mount, this insert enhances throttle response, reduces wheel hop, and sharpens the overall feel of the drivetrain. This results in better power transfer and improved handling during aggressive acceleration, hard cornering, and rapid gear changes.
Durability: Unlike OEM rubber mounts, which can degrade over time due to exposure to heat, oil, and general wear and tear, Powerflex’s polyurethane inserts are built to withstand harsher conditions, offering greater longevity and reliability.
Simplified Installation: The insert is designed to fit into the existing OEM mount, making installation relatively straightforward without requiring complete replacement of the differential mount. This makes it an efficient and cost-effective performance upgrade.
Performance Trade-off: While the Black Series offers a significant performance boost, it can also slightly increase noise, vibration, and harshness (NVH) inside the cabin. This is a typical trade-off for stiffer, track-oriented mounts.
This insert is popular among BMW enthusiasts who want to upgrade their car’s handling for track days or spirited driving, making the rear-end of the car feel more planted and controlled.

For the BMW E60 (5 Series) and E63 (6 Series), upgrading to Powerflex rear differential rear bushings is an essential modification for enhancing the vehicle's performance, handling, and longevity. These bushings play a critical role in connecting the rear differential to the chassis, and their quality directly impacts the driving experience.
Premium Polyurethane Material: Powerflex bushings are crafted from high-grade polyurethane, offering superior durability and resistance to wear compared to stock rubber bushings. This material is less susceptible to degradation from heat, oil, and road grime, ensuring consistent performance over time.
Enhanced Differential Stability: Stiffer bushings help to reduce unwanted movement and flex in the rear differential, which is crucial for optimal power transfer to the rear wheels. This results in improved stability and better handling characteristics during acceleration and cornering.
Improved Handling Dynamics: By minimizing differential movement, Powerflex bushings maintain proper alignment and enhance the overall handling precision of the vehicle. This results in more responsive steering and improved cornering performance, providing a more engaging driving experience.
Reduced Noise, Vibration, and Harshness (NVH): While these bushings are firmer than the factory rubber components, they are designed to minimize NVH. This means you can enjoy improved performance without a significant increase in cabin noise or discomfort, making them suitable for both daily driving and spirited performance use.
Longevity and Reliability: Powerflex bushings are designed to withstand the rigors of performance driving without deteriorating over time. This durability translates to fewer replacements and reduced maintenance, making them a cost-effective upgrade in the long run.
Direct Fit Replacement: These bushings are engineered to directly replace the factory bushings without modification. This simplifies the installation process, though some technical knowledge and tools may be required to ensure proper fitment.
Professional Installation Recommended: Given the importance of the rear differential in the overall drivetrain, professional installation is advised. This ensures that the bushings are installed correctly and that the differential is properly aligned.
Performance Drivers: If you’re looking to enhance your BMW's handling and responsiveness, especially during spirited driving or track events, these bushings will provide a noticeable improvement in performance and stability.
Preventive Maintenance: Upgrading to Powerflex bushings is a proactive measure to ensure the longevity of your differential and related components. If you're noticing signs of wear or if your car is regularly subjected to high-performance conditions, these bushings are a worthwhile investment.
In conclusion, Powerflex rear differential rear bushings for the BMW E60 and E63 are a vital upgrade for enthusiasts seeking enhanced performance and durability. These bushings improve handling precision, increase stability, and contribute to a more engaging driving experience, making them an excellent choice for both everyday driving and high-performance applications.
