A suspension system for use in a laundry washing machine to suspend a tub assembly from a base portion of a cabinet. The suspension system includes a support frame interconnected to an outer tub of the tub assembly and a plurality of isolation damper units for resiliently coupling the support frame to the base portion of the cabinet. The isolation damper units function to allow limited lateral movement of the tub assembly relative to the cabinet while also providing a 'return to center' feature. The isolation damper units are further operable to inhibit rotation of the outer tub relative to the cabinet. Finally, the isolation damper units function to absorb the vibration transmitted through the tub assembly to the support frame so as to minimize transmission of such vibration to the cabinet.
