The swing arm rear suspension components. The trailing arm (7)fits on the splined end of the torsion bar (1) and, as the arm moves up and down with suspension travel, it twists the torsion bar— the 'spring'. The other end of the trailing arm is attached to the axle hub (6), which, in turn, is connected to the lower end of the damper (8). (Courtesy Autodata)
