in those flex pictures he did not have the shocks, or theTraction bar hooked up yet. He said he lost a little movement once those were attached but not much. He is running 7 leaf Wagonner springs Shackle Reversal up front and Revolvers in the rear. The only thing he disliked about the set up is the Revolvers, I think he ended up taking them out, He disliked the way there were unloading on him.
The Z boxes work very similiar, and i have been told the dont have a tendency to unload as much. "MIKE" on the board was running z-boxes in his YJ, i am not sure if he still is.
Karl, a pan hard bar i belive is similiar to a track-bar on YJ, TJ, XJs etc.....CJ's dont have them, and that is always the first thing to be removed from any YJ i have had, I dont htink they are necessary with leaf springs, with Coils you definelty need them
