Don't stress...that dude that rolls down with the 10-12 inch bulletproof show suspension will show up just when you fix that suspension for that 1" back just to lifted higher than the rest.
37's with the regear draws enough attention. I often find people reading my tire size at lights. I mean most of the time my wheel/tire combo is as tall as the prius next to me.
I've driven a 17 tundra with the 6" bracket lift. I do like the procomp 6" coilovers in it but I'm still not satisfied. I thought coilovers alone would be enough but I guess my tastes are getting expensive.
After owning this Ram truck for 6 years I can say suspension mods will always be geared towards travel versus height. Since the DK lift doesn't cut the crossmember I think 4" of lift along with the rest of the will be more than enough. I just don't want blue king coilovers and to hell with pay $1xxx for red
