Totally disagree. I run 1" Just Suspension bars in my Duster. If anything, I'll upgrade them to 1.03's or 1.06's in the future because they're a little on the soft side for me.
As far as bars for the hemi, anything in the .96- 1.03" range will be just fine. If you're looking for a softer ride, go with .96". If you're looking for better handling, go up to 1.03".
