Powerflex BMW F25 F26 Front Radius Arm To Chassis Bush – PFF5-2201
Upgrade the front suspension on your BMW X3 F25 or BMW X4 F26 with the Powerflex Road Series Front Radius Arm To Chassis Bush. This polyurethane suspension bush kit replaces the factory rubber bush (OEM 31106786951) to reduce unwanted flex, sharpen steering response, improve braking stability, and help prolong tyre life. Perfect for road and fast road use, this is a proven handling upgrade for BMW X3 and X4 owners who want precise, consistent geometry and a more connected drive.
At Nforcd we fit these on customer cars and the feedback is consistently positive: tighter turn-in, better stability under load, and improved confidence without the excessive harshness of solid mounts. If your front end feels vague, tramlines, or wears inner edges of tyres, this front radius arm to chassis bush upgrade is the go-to solution.
