The all new and improved Johnny Joint® trac bar for the TJ/XJ/LJ/MJ features an offset Johnny Joint® rod end that puts the bar further forward providing more clearance between the diff and the trac bar. Other features include 1 1/4" x .250 wall 4130 chrome moly construction, a welded in gusset from the bar to the Johnny Joint®, heavy duty adjustor end with urethane bushing and steel insert sleeve, and semi-gloss black powder coat finish. Some drilling is required for installation. The supplied frame bolt is a 5/8", and the supplied housing bolt is 1/2". Both of these holes must be drilled to size to accommodate the heavier duty hardware. A heavy duty nut plate kit is supplied for the housing end. NOTE: This trac bar is intended to be used with a minimum of 2" of lift. It may work on vehicles with less lift with Dana 30 frontends, however, on vehicles with no lift and a Dana 44, 9" or 60 frontend, you may run into a clearance issue. Always check fitment before drilling!
