I have had two rubicons and the selectable locker front and rear is awesome. However, for costs sake, in the Cherokee build I detailed here, I put a Spartan "lunchbox" auto locker in the rear. Really not noticeable on the road, you just have to stay off the gas in turns. Incredibly helpful offroad. Mindless operation, simple installation... perfect for meIf I had kept it, I would have gone to a tru trac up front. Consider driving a locked front end off road before making the decision to put an auto locker in the front. The steering and "handling" if you can call it that at 2mph, is a vastly different animal.

Those handling traits are not present with the tru trac however.
