if i was you i would put the locker in the rear.if you drive on snow or ice when you hit dry pavement the stearing will jurk in your handsand its hard to stear.plus when trail riding most of the time all your wieght is on the rear any way.and next of all i would buy a winch to go on the front first before i would get a front locker.the winch will get you were you need to go and a front locker will not always help you.after you get some money saved up i would get a arb in the front because you can turn it off when needed to be open like on ice and snow.
