A limited slip aka posi trac (chevy term) differential aka diff senses when your tires are 'slipping' more than they should for turning, and lock the wheels together, forcing them both to turn, putting more power to the pavement and letting your car accelerate faster, or helping you get out of a ditch or mud hole, the old style rear differentials were well know to leave you stranded in ditches and mud because which ever wheel had less traction would spin, and the one that had traction would 'slip', leaving you stuck. hope this helped with your question.
If you mean "limited-slip", yes
You buy a posi-trac rear differential.
The limited slip and Trac loc differentials require what Jeep and Chrysler sell as limited slip additive.
Limited slip was an available option.Limited slip was an available option.
That's Fords name for their limited slip differential
The 2010 Dodge Challenger can be equipped with a limited-slip differential, commonly referred to as "Posi-Traction" or "Posi-Trac." However, this feature is not standard on all models; it typically comes as part of specific performance packages or options. To confirm whether a specific 2010 Challenger has this feature, you would need to check the vehicle's specifications or options list.
You can change the rear end of a 1988 Suzuki Samurai to Posi-trac by opening the differential and removing the existing ring and pinion gears. The Posi-trac assembly is then install and the gears put back in place.
Jack one side of the car until the tire is free to turn. If it will not rotate with the trans in neutral (brakes released), the differential is a (sure grip) (limited slip). If the wheel rotates it indicates an 'open' differential..Jack one side of the car until the tire is free to turn.

Posi-traction, commonly referred to as posi-trac in Plymouth vehicles, is a type of limited-slip differential that allows both rear wheels to receive power from the engine, improving traction. When one wheel begins to spin faster than the other, such as on slippery surfaces, the system engages to transfer power to the wheel with better grip, helping to prevent wheel slip. This is achieved through a series of clutches or friction discs that connect the two axles, ensuring better acceleration and stability during turns. Overall, posi-traction enhances performance and handling, especially in challenging driving conditions.
It means that when you get the rear wheels stuck in mud or snow or something, when you have the vehicle in gear and try to move, the rear wheels get equal power so even if one wheel is free, it won't spin. Other names for the same thing is posi trac, or limited slip differential.
my 95 is posi !!
Yes, it could be ordered with GM's Posi-Trac as an option.
