Not sure what you are trying to ask, but pull the cover and you will know what it is. It can be either. It may be listed in the glovebox also.

They can be both, like too much stuff was saying. The factory called these limited slip designs Positraction, if they were limited slip. Otherwise they could have a locker, called NO-SPIN. I think there was another name for factory locker also? I think most of the time, if it was a half-ton truck it would be a positraction /limited slip with clutches, and the lockers were more common in 3/4 and 1 ton trucks.
