Product details
RockJocks adjusable front trac bar for JK Wrangler and Unlimited vehicles features heavy duty forged chromoly construction and features an organic shape that is only attainable via forging to provide maximum articulation capabilities and clearance for all differential options. Due to the rigitiy of the forged bar over a fabricated bar, from a drivability standpoint, you can expect a much tighter and precise feel to how your vehicle drives - that you probably didnt even know you were missing! Adjustable end features pinch clamp. Both ends feature a high articulation Johnny Joint rod end. Intended for us on lifted vehicles, but may also be adjusted to work on stock vehicles. Greasable via zerk fitting. Finish is semi-gloss black powder coat on the bar and gold zinc plating on the Johnny Joint.
