In the USSR, trucks with good off-road capabilities are equipped with a transfer case featuring a two-stage reduction gear. This makes it possible to raise the gear ratio of the transmission and double the total number of transmission speeds. On some vehicles, such as the KrAZ-255B and the KamAZ-4310, the transfer case is connected to a differential connecting the driving axles. This makes it possible for the middle and rear driving axles to rotate at different speeds when the vehicle is traveling over an uneven surface.
