This is my 19' with the front and rear Bilstein set up (keeping the factory front and rear springs in use), and the fronts are set to 2.1" raised. I have no rear suspension height enhancements either, just the new rear Bilstein shocks. I am running on LT 285/65R20 BFG K02's, as well.
Some have indicated that the Bilstein's are stiff and have a harsher ride. I personally haven't noticed a harsh ride at all. Just improved ride quality and better control overall vs the stock shocks and struts.
Or, you could go with the Eibach front adjustable struts and the replacement rear shocks, and then also upgrade with their front and rear springs too.
