Abstract: The invention is directed to a limited slip differential, including a casing having a first clutch surface and at least two case parts, including a first case part and a second case part. An axle receiving side gear is disposed in the casing. A cone clutch associated with the side gear is disposed generally concentrically about a longitudinal axis and has a second clutch surface generally parallel with the first clutch surface. The second clutch surface is disposed at an angle of between about 3.degree. and 7.degree. relative to the longitudinal axis. A biasing device, such as a plurality of compression springs, biasingly engages the second clutch surface with the first clutch surface, and effects a preload force of between about -200 to +500 pounds against the side gear in a direction generally parallel to the longitudinal axis.
