A vehicle suspension including a main frame, front and rear pairs of wheels, and at least one axle extending between the wheels of each pair. Two forwardly and rearwardly elongated members are pivotally carried by the frame to pivot about length axes defined by the members, with each member having front and rear turnec portions. Four supports are on the axles near the wheels, the supports terminally supporting the turned end portions, respectively for pivoting about axes that extend forwardly and rearwardly, during pivoting of the members. Structure is provided to interconnect said two elongated members to transmit torque therebetween. A torsion bar may be activated between the two wheels of the front or rear pairs of wheels.
