Welcome to the CJ addiction!
While this has been discussed before, I am still in the keep or add a front bar camp. I ran without my bar hooked up for awhile, then added the JKS quick disconnects and there is a distinct difference in the way mine drives onroad. The infamous CJ dartiness has diminished to the point of almost gone, I know some will say the bar only controls body roll but I my case it did help. I had completely rebuilt my suspension front to rear before the bar was hooked back up.
