Powerflex BMW E60 E61 E85 E86 Black Series Front Anti Roll Bar Bush 25mm is the ultimate front ARB bush upgrade for BMW handling, steering feel and chassis precision. Built from a 95 Shore performance polyurethane, these Powerflex Black Series bushes lock down the front stabiliser bar to control geometry under load, reduce body roll and deliver a sharper, more consistent turn in on fast road, track, race and rally use. If your OEM rubber bushes are tired, cracked or soft, this direct replacement 25 mm front anti roll bar bush is a proven, durable solution that transforms confidence and response.
We run these Powerflex Black Series 25 mm front ARB bushes on our own builds and customer cars, and the feedback is exactly what you want from a suspension upgrade for BMW E60 E61 5 Series xDrive and BMW Z4 E85 E86. Expect tighter front end control, improved steering accuracy and a more planted feel in quick direction changes and under braking.
