RockJock's Front 2WD Beam Axle Housing Johnny Joint Kit for TJ Wrangler, LJ Unlimited, XJ Cherokee, MJ Comanche and ZJ Grand Cherokee vehicles replaces the front upper control arm bushings Johnny Joint rod ends to get maximum articulation out of your suspension! This kit includes 2 of our 1 in. thick flame-cut steel uprights for the tube side, with the Johnny Joint already installed. This kit has you cut off the top of the stock upper control arm brackets that are on the beam axle and install the new RockJock pieces into the existing bracket bases. You then weld the RockJock pieces to the existing bracket bases. This allows for no welding to be done on the tube, resulting in no warpage of the tube. This kit requires cutting and welding equipment for installation! NOTE: this kit is for use on any factory 2WD beam only!
