rough country....taller than the pc and have no probs with fitment or any issues with the lift. pc fabtech and rc theres your 3 choices anyways lol...its all really up to you and what you want to do. the pc and rc are the same lifts and installs. the rc requires u to cut a small portion off of your rear crossmember in order for the diff to be dropped and bolted whereas the pc uses a half washer instead. rc is prol 2-4" depending on the truck taller front and back all personal preference overall
