ABSTRACT:
The present invention provides a heavy duty suspension system including a frame and a pair of spaced apart trailing arms. The trailing arms each include a forward portion pivotally supported by the frame and extending longitudinally to a rearward portion. An axle has opposing end portions pivotally supported respectively on the trailing arms. A V-rod includes first and second spaced apart ends extending to a common third end with the first and second ends preferably pivotally attached to the frame. The third end is preferably pivotally attached to the axle. The V-rod provides lateral stability and defines a pinion angle with the trailing arms. Preferably, the longitudinal length of the V-rod and the length of the trailing arm from the pivotal attachment on the frame to the pivotal attachment on the axle are of equal length to provide a constant pinion angle during movement of the suspension system.
