Powerflex Poly Bushes Pack - Front Radius Arm To Chassis Bush - PFF5-4101 - BMW F30, F31, F34 3 Series xDrive
Upgrade the front end of your BMW 3 Series xDrive with the Powerflex Front Radius Arm To Chassis Bush kit, part number PFF5-4101. These performance polyurethane bushes replace the soft, ageing factory rubber to deliver tighter handling, sharper steering response and improved braking stability on F30, F31 and F34 xDrive models. Perfect for fast-road driving and daily use, this is the essential suspension upgrade for anyone who wants their BMW to feel precise, planted and predictable.
At Nforcd we have installed and used these bushes on our own builds and customer cars, and feedback has been consistently excellent. Expect a noticeable improvement in front end grip, better tyre contact with the road and far more consistent chassis geometry under load. If your BMW feels vague on turn-in, tramlines, or shows uneven tyre wear, these Powerflex bushes are a proven cure.

- Powerflex Lifetime Warranty for peace of mind
Powerflex poly bushes control the unwanted movement that factory rubber allows as it ages, hardens and cracks. By tightening up the front radius arm to chassis mounting point on your BMW F30, F31 or F34 3 Series xDrive, the suspension can do the job it was designed for. The result is a more responsive front end, improved stability under hard braking and a BMW that tracks true mile after mile.
