A side gear rotatable about an axis, the side gear includes a plurality of gear teeth extending laterally therefrom; a casing member rotatable about the axis, the casing member covering the side gear; one or more bores formed in the casing member, the one or more bores extending in a direction parallel to the axis; and one or more pinions, each pinion having an upper surface and a length, being inserted in a corresponding bore of the one or more bores in the direction parallel to the axis, and having one or more pinion teeth extending laterally therefrom, wherein each pinion is configured to mesh with the side gear via the one or more pinion teeth, and wherein along a first portion of the length of the pinion starting from the upper surface thereof, a size of the one or more pinion teeth is greater than a size of the one or more pinion teeth along a second portion of the length of the pinion.

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.
