Why choose Powerflex polyurethane bushes for your BMW F20 F21 xDrive
Factory rubber bushes soften and degrade over time which can cause vague steering, imprecise handling, braking instability and uneven tyre wear. Powerflex poly bushes control suspension movement so your dampers, springs and tyres can do their job properly. Correctly engineered polyurethane can match or exceed OE levels of noise, vibration and harshness control while offering far greater durability and consistency under load.
Technical highlights
- Offset bore machined into the sleeve replicates OE offset for proper alignment and geometry
- Direct replacement for the original front radius arm to chassis bush
- OE reference for cross-checking: 31126854729
