On the 4 corner coil suspension technically there is no load bearing axle, just the spring in the coil is the load bearing part, and the frame of the vehicle with the control arms.
So, if you put an airbag to support the coil and the weight, your only limit is the tires and the strength of the suspension arm/bushings.
I'm sure he will have wearing and maintenance problems with that setup at some point. Hopefully no catastrophic failures at speed.
You are saying the axle bearings do not bear the weight when using coil springs? And so are not a limiting factor?
I'm no Mech. Engineer but that just doesn't make sense.
