The Firestone Ride-Rite rear air helper spring kit for GM cab-chassis and F350/F450 applications provides adjustable air support to increase load-carrying capacity, stability and ride quality. Air pressure reduces inter-leaf friction and helps prevent bottoming out. The kit includes brackets, hardware, air line and inflation valves for independent adjustment. This application is offered with a no-drill installation using factory holes when specified; install usually takes 1–2 hours and the kit carries a two-year limited warranty.
