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.

Stock rubber control arm bushings give a disconnected and mushy feel to the front suspension, especially when worn, as the bushing deflects more than it should. You get sloppy steering, vibrations, and poor handling which makes the car feel unstable. These urethane bushings are stiffer than stock rubber and will not deflect as much. This helps keep the alignment in check with less variation. The car feels more planted and confidence-inspiring. And a lifetime warranty means you'll likely never have to pay for another bushing ever again! OE / OEM Cross Reference Numbers: 48770A / 48790

Powerflex manufactures polyurethane suspension bushings that are designed to replace OEM rubber bushings. For the BMW F48 (X1), F49 (X1), and F39 (X2) rear sway bar link rod bushings, Powerflex bushings offer improved durability and handling performance. Polyurethane bushings are stiffer than the standard rubber, which helps in maintaining the geometry of the suspension under load, reducing flex, and increasing responsiveness. These characteristics can improve vehicle stability, cornering performance, and reduce premature wear compared to rubber bushings.

Key features of Powerflex polyurethane bushings:

  • Improved Handling: Reduced deflection in the suspension, resulting in more precise handling and better feedback.
  • Durability: Polyurethane is resistant to chemicals, wear, and weather, making it longer-lasting than OEM rubber bushings.
  • Noise, Vibration, and Harshness (NVH): Powerflex bushings are designed to offer better performance without significantly increasing NVH.
  • Easy Installation: Direct replacement for the original bushing, usually without the need for special tools or modifications.

Powerflex bushings are a popular upgrade for enthusiasts looking to enhance their vehicle's suspension performance while maintaining comfort for everyday driving.
