I had had a few leveled with the 2-2.5" kits (RC) and was always happy. This time around, I figured it might be my last new truck for a bit so I wanted to do a little more. I was going to do a 3-4" lift but ran into several tech telling I'd had to change the control arm, larger rims (the stock 17 won't fit) and a few other things. So I went to a dealer that was well known for lifting. After talking we decided to go with a 6" lift and 35" tires on 20's. All in all I love the outcome, maybe 33's when I need to replace the tries?? RC 6" lift, Nitto 12.5x35 Ridge series, XD black 20", AMP power steps.
