O.k it's time for me to replace the worn (90K) factory shocks on my Expy. While I'm at it I want to upgrade the suspension and maybe drop the Expy 2". Has anyone done this kind of upgrade and what product was used? I have seen a kit by Belltech, has anyone used this comany before? What I'm looking for is a smooth, luxury ride, somthing like what a Navigator or Cadillac SUV would feel like or better. Is there any other suspension components that I should replacewhile I'm in there? Any info would be apreciated.
