Firestone Industrial Products Company announced no-drill Ride-Rite air helper spring kits are available for the 2011 Ford Super Duty F-250/F-350, fitting gas (part #2520) or diesel (part #2535) 2WD and 4WD models with the factory in-bed hitch. Designed to mount between the truck’s frame and the suspension, Firestone’s Ride-Rite kits use air pressure to help maximize the truck’s safe load carrying capacity, stability and ride quality. Featuring individual inflation valves for separate side-to-side or front-to-rear adjustment, the air helper springs also assist in leveling off-center loads. Firestone’s no-drill kits use the truck’s factory holes and include all the components necessary for an easy installation that typically takes less than one hour, including the brackets, air springs, hardware, air lines and separate valves. The Air-Rite air accessory system is also available to complement the 2011 Ford Ride-Rite kits, enabling drivers to make instant air pressure adjustments with the push of a button installed on the dashboard.
