The MSOS 4WD system consists of the following components:

The Manual Shift-On-Stop transfer case is a 2-piece aluminum design. The transfer case transfers engine power from the transmission to the front and rear axles. Vehicles equipped with the Manual Shift-On-Stop system allow the operator to choose between 2WD and 2 different 4WD modes. The MSOS 4WD system is engaged or disengaged by rotating the control for both front wheel hub locks from the FREE or LOCK position, then manually engaging or disengaging the transfer case with the floor-mounted shifter.
