The design of these gears, and how they react to varying levels of resistance between the left and right wheels, is what defines an open differential (or “open diff”) compared to a limited-slip ...

Early in the development of limited-slip differential technology General Motors trademarked the term “positraction” (short for positive traction) for its limited-slip differential technology.
