Man, what a long time coming for such a great product. Very cool. The adjustable panhard bar is really a mediocre solution on its own. Like you stated, it is half the solution. Mr T put that panhard at the center of its arc for a reason. I believe if you are serious about a top shelf suspension, this needs to be part of it. I get the OME 2.5" and no more, makes perfect sense getting your truck started on a build.
What I am supporting is this bracket along with modern coil spring concepts, newer ideas in shocks, better caster correction, dc front shaft or part time kit, adjustable upper rears, bigger (anti) sway bars, etc. That is the next-next level. Don't have to, but it is a pretty cool fun way to fuel the addiction with parts that are still "form follows function".
