A suspension system comprises a first hub, bearing means spaced from the hub, a second hub carried within the bearing means and rotatable relative to it, and torsion bar means carried by the first and second hubs and extending between them. At least the second hub is positioned within a stationary, hollow tube of non-circular cross section, with the second hub defining rotary motion limiter means that moves into contact with the hollow tube at a desired limit of rotary motion of the second hub, to prevent further rotary motion beyond the limit. The second hub also carries a transversely extending arm. The second hub, including the limiter means and the arm, is made of a single, cast piece for improved manufacturing efficiency.
