I currently have a corp 10 bolt front with 3:73 gears with 30 spline. I'm plan on keeping it for now. It would be installed in my Daily driver and weekend worrior. I'm running 33 in tire and that as big as i'm going. In my area there mud, snow, sand. I'm using a MM 10,500 lbs hydro winch, 12 bolt rear with a Eaton Posi, Crom-moly 30 spline shafts. Is it worth the expence, Will the 10 bolt hold up to the ECTED. I like the Idea of having limited slip + a full locker when needed!
