Powerflex poly bushes are designed to reduce flex in key mounting points so your suspension and drivetrain components do exactly what they should. That means more consistent tyre contact with the road, improved handling precision, and long-term reliability without the rapid deterioration associated with standard rubber bushes.
- Prolonged tyre life
- Improved performance and handling stability
- Increased safety and braking confidence
- Cost-effective upgrade that lasts
- Powerflex Lifetime Warranty
If you are experiencing imprecise handling, uneven tyre wear, or instability under braking, failing or soft rubber bushes are often the cause. Powerflex offers a proven cure with correctly formulated polyurethane that can match or exceed rubber for noise, vibration and harshness control while delivering sharper response.
We rate this upgrade highly on our own cars and our customers have been consistently pleased with the improvement and value. It is a simple, effective enhancement for daily driven and enthusiast BMW 1 Series xDrive models.
Fitment tip: This is the oval version of the shift arm front bush. Please check bush shape on your vehicle before ordering.
