Disclosed a suspension assembly for a rear two-axle road vehicle is in which a first stabilizer 42 for a driving axle 5 of the rear two-axle set is made less in stiffness than a second stabilizer 52 for a driven axle 6. Even if the vehicle runs onto a curbstone on only one-side rear wheels on the driving axle, the vehicle may steadily get away from the curbstone. The first stabilizer 42 for axle housing 13 supporting the driving axle 5 for rotation is designed so as to have stiffness less than that of the second stabilizer 52 for the axle housing 14 supporting the non-driving axle 6. The stiffness in the stabilizers may be varied, for example, by changing diameters of torsion-bar sections 43 mounted in the axle housings 13, 14 for rotating movement. Even under the road-handling condition where the vehicle runs onto the curbstone on only one side driving wheels on the driving axle 5, the other side driving wheels may be kept in firm engagement with the earth because the first stabilizer 42 is less in twisting moment.
