We'd hoped to use off-the-shelf track bars for JKs or TJs from Skyjacker, but the TJ rear track bar was too short and the JK a little bit too long. Our solution was to build one.

At the top of the photo is the stock TJ track bar with its tie-rod end mount that attaches to the driver side of the frame. The bushing end attaches to the axle on the passenger side of the Jeep.
