This pair of rear lower control arms are direct replacements for weak or bent factory units. Made of 3/16" wall DOM tube, they are more than 2x stronger than the OEM arms! They are equipped with a rubber bushing in one end for isolation of axle noise and xAxis joints in the opposite end for superior flexibility off road. Whether you are replacing damaged OE parts or upgrading for offroad use, these are the arms for you. Need articulation or alignment changes in the front?
