Firestone heavy duty Ride Rite air helper springs are the workhorse of our air helper spring line. The double convoluted air springs offer maximum load support as well as years of worry free service. Ride Rite air helper springs can be installed on most light trucks, motor homes, RVs, SUVs and vans. Ride Rite air helper springs are installed between the frame of the vehicle and the suspension, providing load support through the use of air pressure. Firestone is committed to providing the customer with premium air helper spring kits. Ride Rite air helper springs have become synonymous with quality, durability, and customer support. Each application is specifically designed to maximize the safe load carrying capacity, stability, and ride quality of the vehicle. Ride Rite air helper springs utilize a pair of convoluted air springs which can be adjusted for changing loads. These air springs are capable of 3200 to 5000 Pounds of load leveling capacity. Ride Rite air helper springs enhance the ride by reducing inter leaf friction. Please remember that air springs do not increase the Load Carrying capacity of your vehicle. Ride Rite kits are application specific and are designed for hassle free fitment to the OEM suspension.
