Very happy with the zone 6in lift! Treated my 21 Rebel to a new suspension and wheels. I originally bought the 3.5 ready lift and it was a no go with the OR package. So went with a zone kit some fuel blitz wheels and some 35 nitto ridge grapplers, I give it to zone to my surprise how good the truck rides as good as it was stock. Overall very happy with the whole setup. Thinking maybe should of went 37s. Anyone know of a speedo calibration kit for a 21 Ram? Also anyone looking for a new 3.5 readylift? ..lol
