Firestone Industrial Products Company, LLC offers its Ride-Rite air helper spring kits for the 2011 Chevrolet Silverado and GMC Sierra 2500 and 3500 trucks (part #W21-760-2528).
           
Available for 2WD and 4WD models, Firestone’s Ride-Rite kit uses air pressure to help maximize the truck’s safe load carrying capacity, vehicle stability, ride quality, brake effectiveness, and reduced tire wear, according to the company. The system features individual inflation valves that allow for separate side-to-side or front-to-rear adjustment, which helps keep the vehicle level when carrying off-center loads and maintains ride quality under differing load conditions.
           
The Ride-Rite kit is a no-drill system designed to use the truck’s factory holes and mount between its frame and suspension. Firestone includes 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 company stated. The kit comes with a two-year limited warranty. 
           
Firestone also offers its Air-Rite air accessory system to complement the Ride-Rite kits, enabling drivers to make instant air pressure adjustments with the push of a button installed on the dashboard. 

A pair of Ride-Rite air springs can provide up to 5,000 pounds of load leveling capacity. Note: Air springs do not increase the load-carrying capacity of the vehicle. Do not exceed the vehicle’s recommended Gross Vehicle Weight Rating (GVWR).
