RockJock's Johnny Joint Adjustable Length Front Trac Bar for all JL Wrangler, JL Unlimited and JT Gladiator models features an organic shape that is only attainable via forging! This unique shape provides clearance in all the right places, allowing for maximum articulation and clearance for all differential options. The rigid forged design minimizes (and in some cases completely eliminates) all differential movement feedback to the steering wheel for better overall road feel and drivability.
This bar is intended for us on lifted vehicles and is included in all of our suspension kits, but it may also be adjusted to work on stock vehicles.
Adjustable end features a pinch clamp, as seen in the photo gallery. For maximum articulation, the frame end of the bar features a greasable Johnny Joint rod end and the axle end features a Flex Axis rod end.
Greasable via zerk fitting. Finish is semi-gloss black powder coat on the bar and gold zinc plating on the adjuster end.

Was looking for something specific- gave them a call and was able to order it up, even though it was not on the website.

Boyfriend and I both have a set of the 2.5’ whips for our jeeps and use them every chance we get. They look for show and work even better for light in camp and on the trails. They bolt up similar to a radio antenna and have a quick release feature that we have never seen before but absolutely love. Definitely top 5 favorite accessories we’ve bought for our jeeps, and customer service is just as great as their products!
