This type of LSD has all of the same components as an open differential, but it adds a spring pack and a set of clutches. Some of these have a cone clutch that is just like the synchronizers in a manual transmission. The spring pack pushes the side gears against the clutches, which are attached to the cage. Both side gears spin with the cage when both wheels are moving at the same speed, and the clutches aren't really needed -- the only time the clutches step in is when something happens to make one wheel spin faster than the other, as in a turn. The clutches fight this behavior, wanting both wheels to go the same speed. If one wheel wants to spin faster than the other, it must first overpower the clutch. The stiffness of the springs combined with the friction of the clutch determine how much torque it takes to overpower it. Getting back to the situation in which one drive wheel is on the ice and the other one has good traction: With this limited slip differential, even though the wheel on the ice is not able to transmit much torque to the ground, the other wheel will still get the torque it needs to move. The torque supplied to the wheel not on the ice is equal to the amount of torque it takes to overpower the clutches. The result is that you can move forward, although still not with the full power of your car
GM started offering Limited slip differential in 1957
The front differential is an "open" differential. No limited slip components there.
Is my 2002 Chevy Tahoe a slip differential or a limited slip differential

Limited slip is a locking differential that distributes power evenly to both drive wheels.
The term "Non Limited Slip Differential" is Ford's way of telling you that your differential isn't special. A limited slip differential has clutches in it that stop a spinning wheel (the one that isn't getting traction) and send the power to the one that has traction, so the vehicle can get out of snow or mud. A non limited slip differential can only send power to one wheel at a time, which is the one with the least amount of rolling resistance (the one not getting traction).
The limited slip and Trac loc differentials require what Jeep and Chrysler sell as limited slip additive.
Limited Slip Differential 3.55 gear ratio
F-150 has never had a locking differential until the 2009 F-150 FX4 model. Only choices before the 2009MY was a limited slip or open differential.
