It isn't the back that's bad, it's the front!Do you usually drive around empty? Put a few hundred pounds in the back as see how you like it.If you put a Carli or Thuren front level with good shocks it will ride better in the front.If you put Thuren's rear coils in you will lose payload capacity,I suspect the ride is better though.
IDK if there's 'diesel' springs in the front that's making the thing ride like a tank or just that I need to adjust my expectations.
Thuren doesn't seem to make springs for my gen gas trucks these days. ...at least not in the 'I don't want any more height' springs that I want
