Some Eaton 3/4 ton and GM 14 bolts came with a locker from the factory. In fact I may be wrong but the detroit locker (called a No-Spin) was the only traction aiding device available for an Eaton rear end.
The Eaton automatic locking differential also locks. It is a combination of a locker and a limited slip. It has friction discs that tighten up and lock the rear wheels together when the difference in axle speed is over 100 RPM, however it unlocks at speeds over about 20 MPH. This rear end is commonly called the Gov-lock because of the flyweight mechanism that engages the friction discs.
This is a simplified explination, there is a better one on youtube.
