Abstract: A device for stabilizing against roll in a vehicle has the longitudinally disposed central frame members and a rigid axle is attached at the outer end of each frame member. The central frame members are constructed as trapezoidal shaped torque frames tapering toward their inner opposed ends. The shorter parallel sides which are the opposed inner ends of the trapezoidal torque frames are pivotably mounted at their midpoints to the vehicle chassis and each central frame member is resiliently supported at the opposite longitudinal sides of the chassis by laterally attached links pivotably mounted on a torsion rod the ends of which are movably supported from the vehicle frame.
