all that payload weight you say the air bags "support" is directly transferred to the axle, wheels and tires, thus air bags really support nothing.
No additional capacity is gained by the use of air bags, and other than to be able to level the truck (improve ride) when heavily loaded, they serve no purpose.

Which is EXACTLY what the OEM springs do. I guess the springs "support" nothing too then.
If the axle is rated to carry more than the springs, and the tires are rated to carry more than the springs, wouldn't higher rated springs "support" more capacity? Just like OEM puts heavier springs on the same axle with bigger tires to get a higher load rating?
