The Replacement Heavy Duty Firestone Air Bag # F9294 referenced in your question features a mounting plate diameter of 9 inches. The distance between the two mounting bolts on center is 5-1/2 inches. The bottom mounting surface has a diameter of 9-1/2 inches and uses just one bolt.

I have attached a diagram to assist.

I spoke with my contact at Firestone and they actually are unable to provide a specific maximum capacity for this air spring. This is because the limit will be specific to the trailer it is used on, as this is designed to be a factory replacement part.

If the measurements listed above differ from what you have on your existing spring then this will not work as a replacement. If this is the case please let me know the measurements you took and I will be happy to try and find the correct unit.
