I added some changes above.
Then put lockers in it, this way you have a choice of what type of locker you want.
I live in Saskatchewan, where you can watch your dog run away for 3 days and I am adding the spartan Roxor lockers and the front hubs. I would probably just need the rear one, but I figured 'go big, or go home'; I just might need the locker to 'go home'. I didn't upgrade my tires, I went this route for now.
Def put it in the front and rear, I have a spartan just in my rear different and it's an improvement but you likely won't be happy with just that. The rear end of this thing weighs very little compared to the front. It seems like I'm daily in situations ( wet leaf covered login trails, slick red clay, steep gravel ect) where my rear end is locked up and spinning like a mother%#&#%& and I'm peg leg dancing in the front and going nowhere, even with agressive mud terrain tires on. I think the answer is the locker in the front to suplement the one in the rear. It's not a question of which is better. That's like asking which is better at making babies, males or females, you need both if you really wanna go nuts! Just fyi, I just ordered an ox locker for my front to save me from getting in and out to lock in my hubs.
