BMW 5 Series E39 (1996 - 2004) Rear Subframe Mounting Bush - PFR5-530H These are complete replacement bushes. For inserts to fill the voiding of the original bushes, use PFR5-531. Due to the size of the parts, we can only fit 2 into 1 box and therefore have to supply 2 boxes for a complete car set of 4 bushes. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
