Abstract
A vehicle suspension system assembly for attachment to a vehicle frame having a torsion axle and at least two ground engaging wheels operatively rotatably attached to each respective end of the torsion axle has an attachment member which is adapted to be attached to the frame. An arm is operably pivotally attached to the attachment member along an axis. A torsion axle is received in a torsion axle receiving portion of the assembly at a first distance spaced from the aforementioned axis for selectively receiving the torsion axle. An air bag is operatively disposed between the frame and the arm, the air bag being spaced at a second distance from the axis. A linkage element of variable length, which can be a shock absorber, is operably attached to the frame and to the arm whereby the arm will be held at a predetermined position with respect to the frame and yet allow the arm to pivot about the axis. In a preferred embodiment, the air bag is spaced further away from the pivotal axis of the arm than is the torsion axle.
