Ford Focus Models Focus Mk2 inc ST and RS (2005-2010) Front Subframe Front Bush - PFF19-1218BLK PFF19-1218 Front Subframe Front Bush is machined using POM-H homopolymer acetal (Delrin) to provide minimal deflection and ultra-high wear resistance. It is recommended that PFF19-1219 Front Subframe Rear Bush is fitted at the same time. A small increase in NVH should be expected when stiffening the connecting mounts between the subframe and chassis. - NOTE: Price is for CAR KIT, NOT per bush… Powerflex price their bushes individually, but we have combined the quantities to make it simple!
