Abstract

A suspension system includes a damper assembly to provide an anti-roll capability to a vehicle torsion bar suspension system. The damper assembly is attached to each torsion bar. To selectively couple and decouple the rotational motion of the torsion bars. In one embodiment the damper assembly selectively links rotational motion of the torsion bar anchor arms to transfer an anti-roll force from one suspension link to the opposite suspension link.
