pretty impressed
I recently replaced my factory g80 hybrid locker with a trutrac. I am really impressed by how smooth and quite it is. Theres never any question if its working right (unlike my factory g80). It does good on and light offroad. I do know that if you get one tire off the ground it wont work until you put light pressure to the brakes. But for a stock or mildly modified truck they work great.
