Abstract
A limited slip differential having at least one cone clutch element for frictionally engaging an interior surface of the rotatable differential casing. The cone clutch element has a plurality of clutch engagement surfaces which are disposed about the outside surface of the cone clutch element. Recessed areas are interposed between the clutch engagement surfaces. The total clutch engagement surface area is reduced to between 5% and 15% of the total engagement and recessed surface area of the clutch element to improve the performance of the differential at lower temperatures.
