RockJock's Johnny Joint® adjustable rear trac bar & bracket kit for TJ Wranglers and LJ Unlimiteds includes our 1 1/4" heavy wall 4130 chrome moly trac bar that features our 2" Johnny Joint® rod ends at both ends, and our heavy duty trac arm relocation bracket that allows the trac arm to be installed at the proper angle and position. The heavy duty steel bracket bolts onto the rear axle housing and relocates the trac bar pivot point. The trac bar then bolts up to the stock Jeep frame bracket and the new RockJock housing bracket.
