Rear axle stabilizer

A stabilizer for use in conjunction with the rear axle of a vehicle having a chassis, wherein said axle is flexibly mounted to said chassis, comprising a U-shaped stabilizer bar, having a midsection and two arms, and tie rods pivotally mounted to each of said arms, said stabilizer being pivotally mounted between said chassis and said axle by said tie rods and said midsection, said stabilizer having selected dimensions and mounting locations to form an angle between said tie rods and said arms, measured in a plane perpendicular to said axle, of approximately 90.degree. when said vehicle is assembled and fully loaded, resulting in a first leverage for converting rolling forces of said vehicle into torsion forces on said stabilizer bar, and causing said stabilizer bar to exert a first roll-restoring moment between said chassis and said axle, said angle increasing to more than 135.degree. when said vehicle is unloaded but fully assembled, resulting in a second and lower leverage for converting said rolling forces into torsion forces on said stabilizer bar, and causing said stabilizer bar to exert a second and greater roll restoring moment between said chassis and said axle.
