Your choice will be simple... ~1.75" leveling kit for the front (Rocky Road and Tough Country), or a ~ 2.5" lift front/rear from Rocky Road. No one else has yet been brave enough. I got the leveling kit and love it, although if I had to do it again I would consider the full front/rear lift.
The RR 2.5" lift is a full front and rear lift kit, It actually gives you more lift in the front and a little less in the back to even it out a little bit. It's a different kit than the 1.75" leveling kit which is just the 1.75" spacers for the front struts.
