The Firestone Ride-Rite rear air helper spring kit for 2004–2012 Chevy/GMC Colorado and Canyon (2WD/4WD, not ZQ8) supplies adjustable air support to improve load capacity, stability and ride comfort. Air pressure reduces inter-leaf friction and helps prevent bottoming out. The kit includes brackets, springs, hardware, air line and inflation valves for independent side-to-side or front-to-rear adjustment. This application requires drilling for installation; typical install time is 1–2 hours and a two-year limited warranty applies.
