I read the instructions for my Lock Right and it says that if you have a locker in the front and in the rear, the rear tires will have 70% of the traction. I suppose it has something to do with that when you accelarate the weight shifts and the front of the car lifts. Anyway, since I only have one locker I was thinking about putting it in the front so that when driving on the street I can just unlock my hubs and I won't have any handling problems. But after reading the above I'm not sure anymore. I have a 10 bolt diff. front and back.
