Doug,
My truck sits level on spacers and I have rubbed 285 buckshot mudders. My axle isn't centered (stock track bar) so that doesn't help. The rubbing is on the control arms and a lift won't solve that. You can go with aftermarket arms but that makes the lift a lot more expensive. To do it right, you need spacer or new coils, new shocks, new control arms and a new track bar. That will get your geometry back into check but costs about 10 times what just the coils do. I'm doing mine in stages... track bar is next. Aftermarket wheels with different backspacing helps too, but can rub the fender if they are spaced too far outward and you know how the PA police feel about tires sticking outside of the fenders!
So I guess the answer is, they may rub, depends on how you plan on your driving style. I try to keep my truck away from full lock on the steering. Some guys claim they never had any rub issues.
