Abstract
Abstract A friction reducing automotive suspension stabilizer bar includes a combination torsional and bending reaction segment running generally transversely across the vehicle and pivotally mounted to the chassis of the vehicle and left and right crank arms with each having a first end attached to the torsional and bending reaction segment and a second end adapted to be attached to a telescoping strut. Bearing means are provided for attaching each of the second ends of the stabilizer bar to the inboard side of a telescoping strut such that the torsional and bending reaction segment of the stabilizer bar will react to both torsional loading resulting from jounce and rebound movement of the suspension as well as to bending loads resulting from transversely directed forces imposed upon the second ends of the crank arms by the telescoping struts.
