Original EquipmentSynchronizer Ring

The transfer case synchronizer allows the speed of the front drive shaft to be synchronized to the speed of the rear drive shaft when shifting from two-wheel drive to all-wheel drive to provide the shift on the fly function. The synchronizer assembly also includes a neutral position where both the front drive shaft and the rear drive shaft are not engaged to the vehicle transmission to allow for vehicle towing.
