a front locker can result in turning issues once in a while. it's the trade-off for the insane amount of traction you'll get. but automatic lockers are designed to engage and disengage automatically as power is applied. spools suck. they are engaged 24/7.
plus if you really didn't like it, they come right out as easy as they went in. :thumbsup:
If you have a posi rear, I say drive it like that for a while. if you find yourself getting stuck a lot, then maybe shoot for the front locker.
