Unlocking diffs are awesome. I have one in the front of my 1:1 Jeep (to the left). A locked front end wants to push FORWARD, not turn, due to the tires grabbing at the same speed. An unlocked diff allows the tires to turn at different speeds while the rear tires are locked (DIG) which makes for one hell of a sharp turn. It practically, and in some cases actually does, turn the rig around on a dime.
