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.

The BMW E46 / E36 / Z4 / X3 Rear Trailing Arm Front Bushing by Powerflex is a precision-engineered suspension upgrade designed to improve the handling and durability of several popular BMW models. This bushing replaces the factory rubber bushing located at the front of the rear trailing arm with a high-performance polyurethane version.

Product Features:

  1. Polyurethane Construction: Unlike standard rubber bushings, Powerflex bushings are made from durable polyurethane, a material known for its superior resistance to wear, heat, and degradation from oils and contaminants. This leads to a longer lifespan and more consistent performance over time.

  2. Stiffness for Enhanced Control: The polyurethane bushings provide increased stiffness, reducing unwanted flex and movement in the rear trailing arms. This helps to maintain better control of the rear wheel alignment, resulting in more stable and predictable handling, especially during cornering, acceleration, and braking.

  3. Reduced Deflection: By reducing the deflection of the rear trailing arms, these bushings help to improve traction and rear suspension geometry. This makes the car feel more planted and responsive, reducing wheel hop and improving grip under load.

  4. Direct Replacement: The Powerflex bushings are designed as a direct replacement for the factory-installed rubber bushings, meaning they will fit perfectly into the existing suspension setup without requiring modifications. This makes installation straightforward while significantly enhancing the suspension’s performance.

  5. Longevity & Resistance: Polyurethane bushings are highly resistant to common automotive contaminants such as road debris, oil, water, and heat. This makes them a more reliable choice for drivers looking for a long-term solution to suspension wear and tear.

Compatible Models:

  • BMW E46 (3 Series, 1999-2006)
  • BMW E36 (3 Series, 1991-1999)
  • BMW Z4 (E85/E86, 2003-2008)
  • BMW X3 (E83, 2003-2010)

Advantages:

  • Improved Rear-End Stability: Provides more precise alignment and control of the rear suspension, resulting in sharper handling.
  • Durable & Long-Lasting: Outperforms rubber bushings in terms of longevity and wear resistance.
  • Enhanced Ride Quality: Reduces unwanted suspension movement, improving driving dynamics and cornering performance.
  • Easy Fitment: A direct replacement for stock bushings, with no special modifications required.

For drivers seeking a more connected and performance-focused feel from their BMW, the Powerflex Rear Trailing Arm Front Bushing is a significant upgrade over stock rubber bushings, delivering improved handling, reduced wear, and enhanced driving enjoyment.

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.

The Powerflex silicone grease is the only lubricant we suggest for long, squeak free operation. The lubricant contains silicone that resists heat and water and keeps a more constant viscosity to allow it to stay in the bushing as temperatures increase. The lubricant also does not lose it's lubrication properties over time like an anti-seize type lubricant. Each pack will lube 2 large bushings or 4 small.
