I heard from a buddy that the Rancho 4" actually lifted the truck 5.5"s. I think someone put that in a thread a while back also but I couldnt find it. I wanted to ask you because you actually have the lift already? Also what kind of trac bars do you have and where did you get them. I am still undecided between the rancho 4 and the fabtech 6. Running 33s right now would have to buy new tires for sure with fabtech.
