A suspension assembly for a motorized vehicle includes a rotatable drive-unit driveshaft extending outwardly from an aperture of a drive unit. A first portion of a dropcase is pivotally coupled to the drive unit. A first end portion of a dropcase driveshaft is coupled to the drive-unit driveshaft such that rotation of the drive-unit driveshaft causes a corresponding rotation of the dropcase driveshaft. A second end portion of the dropcase driveshaft extends outwardly from a second portion of the dropcase and is suitable for coupling to a wheel hub. A pivotal-coupling assembly pivotally couples the dropcase to the drive unit. The pivotal-coupling assembly provides a pivot axis between the dropcase and the drive unit along a longitudinal length of the drive-unit driveshaft.
