If you plan on only street driving it.....YES
If you plan to do serious wheeling......NO
8 inch lift springs are going to be stiff, so that will help keep the truck from flexing too much....but offroad you are still going to get enough flex to get some fender munchage. The front is the most troublesome, the stock opening is really small and it has that "fang" on the leading edge that wants to hit the tire too. The turning of the tire (when flexed) requires a LOT more room than what you think you need by just looking at the truck parked with the lift and big tires installed.
My truck runs 38's with about a 4" spring lift...1" worth of longer shackle-type mods, and a 2" body lift. I needed lots of trimming and still don't have inner fenderwells up front.
