    Posi trac is a limited slip for the rear end. There are different kinds, but most consist of clutches to link both axels together so they both drive at the same time, rather than haveing one axel drive while the other one slips. Randys Ring & Pinion is a well respected outlet for these parts you need & is also one of the best priced..
