BMW X Series X7 Series Front Radius Arm Bush - PFF5-2801 The OE rubber splits and the hydraulic fluid escapes, reducing the bush's ability to dampen and resist load, leading to knocking, vague handling and braking instability. PFF5-2801 Front Radius Arm Bush is a new replacement solution, meaning you can now replace the bush alone without the expense of replacing the costly OE control arm in its entirety. Made in our Black 95A durometer material, they are paired with stainless-steel inner sleeves and CNC-machined outer shells for strength and improved load distribution to revive the feel and handling of your 2.3-tonne cruiser. Each bush has a knurled bore for grease retention and a low-resistance operation, resulting in better braking stability, more precise steering and improved tyre longevity. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
