Powerflex PFF5-4101 Polyurethane Front Radius Arm to Chassis Bush for BMW F20 F21 F22 F23 F30 F31 F32 F33 F34 F36 xDrive (Tension Strut/Lower Control Arm Rear)

BMW F2x F3x xDrive Front Thrust Arm Rear Mount Poly Bush Kit - PFF5-4101

Transform front-end precision and braking stability on your BMW xDrive with this uprated polyurethane set for the front lower arm rear mounting point. Designed to replace the soft OE hydrobush, this kit keeps alignment true under load, boosts caster stability and gives you crisp steering feel on road or track. The sleeve is machined with an offset bore to mirror the factory eccentricity, so you keep the correct geometry while dramatically cutting unwanted arm movement.

We run these on our own cars and have fitted them for countless customers. Feedback is consistently positive: tighter turn-in, more confidence under hard braking, improved tyre contact and far better consistency than ageing rubber. If you want an all-wheel-drive BMW that feels planted and responsive, this is a superb upgrade or OE-quality replacement.

Highlights

• Sharper steering response and reduced wander at motorway speeds
• Greater braking stability with less dive and squirm
