The Detroit Locker maximizes traction by delivering 100% of the torque to both drive wheels. It is engineered to keep both wheels in a constant drive mode, and has the ability to automatically allow wheel speed differentiation when required. No other performance differential has the reputation for delivering traction in mud, snow, rocks and on the track.
I have a Chev 77 K30 3plus hooked to a 400hp 396 BB. In 4Hi the truck was more or less useless. Against the advise of many "pros" I installed this into my 14 bolt rear diff. Was done in about 2 hrs including beer breaks. Haven't looked back since. Places I go in 2by will blow your mind. Have had it for 3 years now. Keep inspecting unit for wear or chunks, still looks brand new. No visible wear. Hunting, firewood, mud, no fricken problem. Have only heard it unlock once and yes that could be felt as well. Two elk n a moose in the back with both tires chained up spinning up hill for a mile in 2.5 feet of snow at -30c, nay sayers, YOU WERE WRONG THIS LOCKER ROCKS. I cant find anything bad to say, if there was, I would comment on it, buy it for your open 14bolt Chev, cant go wrong for cheap traction upgrade..
