What spring code do I need?

[Beast Of Burden]

My trucks sits too low for me but I dont want to lift it too high because I need to plow with it. I would like to run 315/75/16's on my stock wheels but im not sure about tire rub while plowing. right now my springs are more "n" shapped than "u" shapped, so what spring code is "u" shapped? I called around to some local junk yards and they have V and B code springs

Could I even plow with 315's on stock wheels, I just thought about what some people have told me about tire rub with 315's and a leveling kit on stock wheels. When I raise the plow and the front end drops would I be able to turn?

Either get stock snow plow springs..X codes or you could get a 2-3" hanger kit.
I'd get the X codes..X — 2C34-5310-AFA, 6,000 lb. 2C3Z5310AF PM if I can help.
