These guys know off road suspension, I got an education! I'm real happy with what I built. It floats over bad terrain.
My panhard bar was an after thought. It was a design flaw fix. Not a bad one either, I could have gone back to square one or installed the bar..... my choice was the bar. If I built another one it would be a true 3 link. On the up side I may have gotten more articulation out of the set up the way it is (drag links rotate at both ends) .... I have a true 10 inches of suspension at each corner
