i think stock uppers and lowers and db might be a good combo but i idk you are just going to look at it, i have re db and i have installed rc db and the only difference is the support on it rc uses self tapers and are shorter and re go all the way back to the cross member bolts. no difference in control arm brackets.

and for the man that said who it doesn't effect ground clearance pleas tell those to the rocks i have hit them on at moab

 

Well the leafs out of the box which is only a year and a half used came as 4"s so when it settles it'll be even but with the old coils and leafs I probably gained about 4.5"s compared to stock, my old tires were 235/75/15 new ones are 31/10.5/15
