The suspension includes leaf springs () disposed on opposite sides of the vehicle, each of which is coupled to the vehicle frame at first and second ends () and to an axle beam () intermediate the first and second ends. The suspension also includes first and second arms (), each of which is pivotally coupled to the axle beam at a first end () and to the vehicle frame at a second end () proximate one of the ends of a corresponding leaf spring. The suspension may further include a torsion bar () extending between and coupled to the first and second arms.
