A limited slip differential is fitted to vehicles where the terrain they have to cover requires both drive wheels to be able to give simultaneous traction. Early models were fitted with cone type limited slip. Later models have the plate type.

Both types operate on the same principle. The side gears are connected by a friction type clutch to the casing under moderate spring pressure. When the differential is called upon to function, such as when going round a corner on normal roads, the clutch will slip and permit the normal differential operation between the two drive shafts. This is not the case however, if power is applied. When the differential is in operation and power is imparted, there is a tendency for the pinion and side gears to separate. This forces the covers tighter onto the casing and locks the differential On the plate type there are two sets of pinion gears. The shafts of these are located in grooves between pressure rings. When the differential forces occur the shafts ride up in the grooves and apply the pressure without reducing the mesh depth of the pinion and side gear teeth as happens on the cone type.
