Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

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: For use with factory 21.5mm sway bar only

The Powerflex 20mm Rear Sway Bar Bushing for BMW E34, E36, and E46 models is designed to provide a significant upgrade over the stock rubber bushings, enhancing the performance and responsiveness of the rear suspension system. This replacement bushing is crafted from high-quality polyurethane, which offers several key benefits.

Key Benefits:

  2. Long-Lasting Durability: These bushings are engineered to withstand wear from exposure to oil, heat, and road debris, ensuring that they maintain their integrity and performance longer than traditional rubber bushings.
  3. Improved Steering Feedback: By reducing unwanted movement in the sway bar system, these bushings allow for more precise steering responses and a better overall connection between the driver and the vehicle, enhancing control during spirited driving.
  4. Direct Fit for Easy Installation: Specifically designed for BMW E34, E36, and E46 models with a 20mm rear sway bar, these bushings ensure a perfect fit and straightforward installation without the need for additional modifications.

This upgrade is ideal for BMW owners looking to improve the handling characteristics and durability of their vehicles, making it suitable for both everyday driving and performance applications on the track or road.

Upgrade your vehicle's handling performance with Powerflex polyurethane sway bar bushings. Unlike OEM rubber bushings that prioritize comfort over precision, Powerflex bushings are designed to reduce body roll and enhance cornering confidence.

Sway bars play a crucial role in transmitting cornering forces from the outside wheels to the inside wheels, ensuring your vehicle stays flat during sharp turns. However, OEM rubber bushings can lead to unnecessary body roll due to their flexible nature, compromising the effectiveness of the sway bars.

Powerflex polyurethane bushings offer a firmer alternative to OEM rubber, providing improved bar retention and minimizing sloppiness during cornering. This results in enhanced handling capabilities and a more engaging driving experience.

As the leading suspension bushing manufacturer in Europe, Powerflex leverages its expertise in polyurethane materials and advanced manufacturing techniques to produce premium bushings that meet exact-fit standards. Whether you're driving on the street or hitting the track, Powerflex bushings are built to last longer than OEM rubber counterparts while delivering superior performance.

For easy installation and prolonged service life, we recommend using Powerflex Copper Grease PCG1. This grease helps reduce squeaks and ensures optimal performance of the bushings over time.

Choose Powerflex street bushings for daily-driven vehicles with occasional autocross or track outings. For dedicated track cars seeking maximum stiffness, Powerflex Black Series bushings with a 95A durometer polyurethane material are the ultimate choice, offering 25% more stiffness than street bushings.

To top it off, Powerflex stands behind its products with a lifetime warranty for the original purchaser, providing peace of mind and assurance of quality and durability. Upgrade your suspension with Powerflex and experience the difference in handling performance.
