A spring beam suspension system includes a hanger; a flexible spring beam extending between the hanger and an axle; and a generally U-shaped pivot bracket secured to the spring beam, the pivot bracket including opposing legs which are pivotably attached to the hanger. Another spring beam suspension system includes a lift actuator which lifts the axle by applying a biasing force to a portion of the spring beam which extends forward from the hanger. Yet another suspension system has a bushing secured in the hanger, whereby the beam pivots relative to the bushing.
