Powerflex PFF5-4102 Poly Bushes - BMW F-Series xDrive AWD Front Wishbone Inner Mount Upgrade

Refresh the front end of your all-wheel-drive BMW with the Powerflex PFF5-4102 polyurethane bushes. Designed for the inner mounting point of the front lower wishbone to the body, this Road Series upgrade tightens up steering feel, improves braking stability and keeps suspension geometry consistent under load across real-world road and fast-road driving.

Built to outlast tired factory rubber, PFF5-4102 is around 8 percent stiffer than the OE part, helping reduce unwanted arm movement for a sharper, more predictable drive. Expect better road holding, crisper turn-in, increased safety and longer tyre life without the harshness you might associate with track-only components. It is a direct replacement bushing kit for xDrive AWD F-Series BMWs listed below.

Why this upgrade works

• Uprated polyurethane bushings for the front arm-to-body location on AWD models
• Approx. 8 percent increase in stiffness versus standard rubber for tighter control
• Consistent alignment control under acceleration, cornering and braking
• Road Series compound for everyday use and spirited driving
• Direct-fit replacement to refresh a common wear point and restore precision
