thanks for all the info guys, I used to live in Arizona and found out at times that getting to my hunting area's would have been less nerve racking if I had lockers. As i'm now living in the great sand and swamp of North Carolina, i simply dont want to be stuck in a situation where my wheels are spinning but i'm sitting. I just got my 2nd bronco 1996 XLT, 351w, on 31's. previous was a 1991, 302, 33's, 3 inch lift, rhino lined inside, beater outside. I'm looking at putting on new front a rear bumpers, potentially replacing the hunter green paint on the lower half (it's two toned) with hunter green Rhino lining, as well as adding a soft top. I was thinking of adding a locker in the front and Limited slip in the rear, may still go with the L/S in the rear. I'm thinking of the Yukon DuraGrip Ford 8.8", 31 spline. any recommendations on this product. Thanks guys
