Expert Reply:

The Firestone Standard Air Spring, # F6401, has a maximum load leveling capacity of 2,500 lbs each. When using 4 of these springs on your tandem axle trailer, they will provide you with a maximum load leveling capacity of 10,000 lbs and would not be effective if the trailer is loaded over 10,000 lbs. This spring is designed to be used with Firestone Ride-Rite kits on vehicles and were not designed to be used on large trailers.

If you are looking for suspension enhancement that matches the weight capacity of your axles, then I would recommend looking at the Timbren Rubber Springs, # TTRA15252. These springs have a 10,000 lb capacity and two sets would work well on your trailer.

Keep in mind, adding air or rubber suspension enhancement springs to your trailer suspension does not increase your trailers weight-carrying capacity.
