Abstract
A limited slip differential for a vehicle includes a differential gear case, and first and second side gears supported by the differential gear case. The first and second side gears are engaged with each other along an interface, and the interface a non-flat profile, such as a conical or frustoconical profile. Depending on the angle of the conical or frustoconical profile, a torque bias ratio (TBR) of the limited slip differential can be adjusted.
