what is "Marvelous Mystery Lift" i've searched all over and everything leads me to a link to a page that apparently no longer exists. i really need to get my truck lifted and don't want just a body lift. is the 6" superlift kit for all crew cab models or zr2 only? anyone know abot the 5" trailmaster lift? i've already got some tuning done and 31x10.5x15s on and just need a little clearance.
