Need some advice on a good reliable locker for the rear end of my truck. Truck has 3. 54 gears and has a factory LS Diff that is worthless. I dont do alot of serious offroading, but when I do venture off road for whatever reason it would be nice to have both back tires push the truck instead of the right rear. Is there anything on the market that provides good locking capabilities but is flexable on U turns and city street driving. Any advice is greatly appreciated.
