a fairing assembly is suitable for use with a heavy duty vehicle having a cab mounted to a frame , wherein relative motion occurs between the cab and the frame during vehicle operation . the fairing assembly extending downwardly from a lower portion of the cab and includes a fairing panel and a hinge for hingedly connecting an upper portion of the fairing panel to a lower portion of the cab . the hinge defines a hinge line extending in a generally longitudinal direction . the fairing assembly further includes a link having a first end rotatably connected to a lower portion of the fairing panel and a second end rotatably connected to the frame . the link substantially limits rotation of the fairing panel about the hinge line and rotates relative to the fairing panel to allow for relative motion between the frame and the cab .
