For use with a differential, annular friction discs configured to insure mating frictional contact between adjacent discs along a desired line of contact. The discs are selectively connected to either a side gear or the housing of the differential. At least one of the friction discs contain a relatively flat annular surface which is located on the opposite side of another surface having a pair of radially spaced annular projections for engagement with a relatively flat annular surface of an adjacent disc. At least one other friction disc has a relatively flat annular surface with an opposed surface having an annular projection spaced radially intermediate the radial space projection on the previously mentioned disc. The single annular projection is for engagement with a relatively flat surface of an adjacent friction disc. The discs are located between the side gear and the housing of a differential. In response to axial movement between the side gear and housing, the adjacent surfaces of the discs move into frictional contact with one another to retard relative movement between the side gear and housing. In this manner, the differential retards relative rotation between the side gears of the differential. The given configuration of the discs insure proper engagement between the mating relatively flat surfaces of the discs.
