The bigger axles is def a plus, but going to springs will be a minus. You already have half the work there. Just go with coils, You'll be happier.

And yeah, not too many places you'll need anything bigger than 38's, but I hope you plan on going to bigger and better places than Uwharrie to test that thing. With the same lift, I'd def go for 40's, you can def pull it off. Best of luck
