Abstract: A vehicle suspension system includes a spring, a neck assembly, and a rod. The neck assembly has an outer shell housing a hollow stem having an upper end and a lower end. The stem is rotatable respect to outer shell. The upper end is coupled to an upper bracket having a control arm pivotally coupled thereto. The lower end is coupled to a lower bracket having a linkage pivotally connected thereto. The rod has a first end coupled to the spring and a second end coupled to the linkage. The rod extends through the hollow stem. The linkage is further coupled to a wheel assembly.
