Abstract: A stabilizer for a vehicle having a chassis and transversely-positioned wheel supports mounted for vertical movement relative to the chassis. The stabilizer has a pair of levers and means for pivoting these levers to the chassis about horizontally spaced longitudinal axis. The levers are formed to dispose their normally lower ends adjacent to the wheel supports. Means are provided for slidably connecting the lever ends to the wheel supports to cause conjoint vertical displacement of the lever ends and the wheel supports. The levers are formed with juxtaposed normally upper ends and means are provided for pivotal connection of the upper ends to provide conjoint vertical displacement.
