A differential assembly, comprising:
- a differential comprising:
- a shaft extending from outside of the differential housing to inside of the differential housing;
- a differential housing configured for rotation, the differential housing comprising:
- an outer surface extending around the differential, and
- a first end cap fastened to a first end of the differential and a second end cap fastened to a second end of the differential, and the first end cap, the second end cap, and the shaft extending beyond the outer surface of the differential housing;
- a first driven gear and a second driven gear disposed about the outer surface of the differential housing, the first driven gear positioned within a first slot formed by the first end cap and the shaft, and the second driven gear positioned within a second slot formed by the second end cap and the shaft;
- a first active gear and a second active gear coupled to an output shaft, the first active gear engaged with first driven gear, and the second active gear engaged with second driven gear;
- and
- a movable shifting collar disposed around the differential housing, and the shifting collar engaging the first driven gear with the differential housing in a first position and engaging second driven gear with the differential housing in a second position.
