•  There are two types of differentials available, standard differential and limited slip differential (LSD).

•  The purpose of the LSD is to provide driving force to both tires by preventing either tire from slipping.

•  With a standard differential, if a tire starts spinning due to poor traction such as mud or snow, the driving force is exerted on that tire by the action of the differential. With the LSD, the differential action is automatically limited and driving force is exerted on both tires.
