Description

Track Bar

RockJocks adjusable front trac bar for JL Wrangler, JL Unlimited and JT Gladiator 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.

Note for Australian and European Markets

Unless otherwise stated, this product may be engineered for use in Left-Hand Drive vehicles. Steering components, pedals, shifters, linkages, wing mirrors, instrument clusters, panhard rods/traction bars, drag links, brake boosters, brake or clutch lines, accelerator cables, heater cores, some master cylinders and adjacent parts can vary between LHD and RHD configurations. In some models compenents such as windscreen wiper arms, motors and linkages could differ in their size and orientation. Items such as floor mats & dash mats may have differences in their structure around the front row (or padding in different locations). In many cases items are identical depending on the design of the vehicle and part, but may have differing mounts, lengths or bolt patterns. Carefully review the product images and details to ensure suitability for your vehicle, or contact StreetFX support if you are unsure. Returns are not accepted for special order products.

Rock Jock Johnny Joint front adjustable trac bars replace the front traction bars on some stock Jeeps with adjustable-length units. They're designed to center the front axle assembly under the vehicle after the installation of a lift kit and/or the springs settle. The traction bars are made from 1 1/4 in. heavy-wall DOM tubing and use a 5/8 in. bolt on the housing for extra strength.
