Firestone Ride-Rite part # 2250 is your best choice for helper springs. These air bags mount between the frame and suspension to help the stock leaf springs support oversized loads. When extra weight from a load is applied you will fill these bags with air until the vehicle is back up to stock ride height giving you equal, if not better, ride quality than when unloaded. Each kit comes complete with one pair of air bags, custom vehicle specific mounting brackets, air lines, air fittings, and all the mounting hardware needed for installation. Ride Rite kits install in about one hour with no special tools required and are designed to fit with most gooseneck or 5th wheel hitches.
