Abstract
Provided is a tandem lift auxiliary axle suspension assembly for vehicles which can be selectively raised and lowered to adjust the overall vehicle weight to axle ratio. A tandem wheel mount is connected with a pair of torsion rods to a hanger depending from the vehicle frame. An air spring mounted between the beam and the frame dampen axle movement during use. A lift spring is mounted between the hanger and the torsion rods, or other components of the assembly to selectively raise and lower the tandem axles for ground engagement as needed to decrease the weight to axle ratio.
