Gear Help

I have an 03 F250 crew cab auto trans 7.3L with a 10" lift and recently went from 40's to 37's because the 40's were chewing up my fenders. All the work was done by the previous owner. I don't tow a lot and I want to run good down the freeway. The truck currantly has 5.13 gears. I am confused on which will be the best as I don't want to do it twice.

I say 4.10's, I've been running 35's for over a year now on my red truck, with 3.73's and it's doing ok, still pulls fine. If you're running an auto trans, maybe you would want 4.30's, but I'd go for the 4.10's for the lower RPM's at highway speeds.
