So I have a 2016 2500 with the 6.4 and I want a little more height. Thinking about doing coil spring spacers and doing 2.5" in the front and 1.5 or 2" in the back. I don't want it totally level so that it doesn't sag too much when towing just a little more level. I know I will need to address the front shocks but what about the rear shocks and front track bar? Any other things to consider? And of course I don't want to sacrifice the ride and handling
