Abstract:
A variable speed front differential assembly for a vehicle is provided including a first side shaft, a second side shaft, and an input shaft. An offset differential case houses a differential mechanism engaging the first side shaft and the second side shaft. A speed selection assembly is movable from a first speed position to a second speed position. A speed reduction assembly is mounted adjacent the offset differential case. The speed selection assembly directly engages the offset differential case housing when in the first speed position such that a 1:1 drive ratio is achieved. The speed selection assembly engages the offset differential case through the speed reduction assembly when in the second speed position such that an increased drive ratio is achieved.
