Listen if you have no desire to off road and main purpose is just to fit the 265/70/17 on, then I would highly recommend leaving the suspension alone and just modifying the pinch weld. With that one modification and the Mamba Mr-1's you can fit the 265/70/17 with no problems. IMO there is no need to put the wear and tear on your front end if you do not plan on taking it off road.
However if you are dead set on lifting it, then ask your self if you like a little rake or you prefer level. If you want level, then the RC is the way to go. If you want to keep a little factory rake, then I would recommend the Rocky Road Outfitters 2.25 inch lift. Either way go with the Bilstein HD's on all 4 corners.
If you go with the RRO, Bilstiens, Mambas and 265/70/17 then you will look something like this:
