RockJock’s Johnny Joint Adjustable Length Rear Trac Bar for all JT Gladiator models is an easy, bolt-on component that makes a huge difference! This bar can be used on a stock JT, on a JT with our Suspension System, or anything in between!
Trac Bar features greasable, RH/LH adjustable narrow Johnny Joint rod ends on both ends, which provide for maximum articulation as well as allowing for adjustment of the bar on the vehicle, without either end having to be removed.
Finish is semi-gloss black powder coat and the forged adjuster end is finished in gold zinc plating.
