Firestone Heavy-Duty Ride-Rite Air Helper Springs are the workhorse of the 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, motorhomes, 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.
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 3,200 to 5,000 lbs. 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.
