A vehicle suspension system comprising a frame and a pair of levers carried by the frame. Each lever is pivotally mounted for swinging movement on an axis extending transverse to the frame. A pair of forward-extending beams and rearward-extending beams have pivot connections with a respective lever and support a forward and rearward axle. Two forward springs and two rearward springs are each interposed between the beams and the frame. A pair of torque arms is carried by the frame forward of the forward-extending beams. Each torque arm has a first pivot connection with a respective beam and a second pivot connection with the frame forward of the first pivot connection with the beam. The torque arms function to restrict pivotal movement of the beams about their respective pivot connections with the levers thereby to reduce torsional forces applied to the forward axle.
