Smart ForTwo 451 (2007 - 2014) Rear Beam Mount Bush - PFR68-130BLK The OE rubber bush is only supplied as part of the rear axle beam assembly making it extremely expensive to replace ( 300 plus labour) when it fails. We are now making a two-piece voided bush, offering a cost-effective replacement solution that can be installed without removing the beam. With this one bush being the main mounting point for the rear axle, its operation is vital for rear-end control. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
