Air bags improved ride while not towing?

"You have reduced the load capacity significantly by removing the overloads, regardless of the airbags." You'll never convince me of that one! So all the trucks, busses, RVs and any vehicles that were converted from springs to air don't have any load capacity? I did it and it works great. The bags are good for 5k lbs all by themselves and the bed is the same height loaded as it was empty. I added capacity AND got a better ride loaded. I had Airlift on my 97 and FS on my 03 - both double bellows. My neighbors' truck is the identical twin to mine and he has Airlift single bellows and the travel looks like it would be really short.

I'm with you on this one. Not that airbags increase a vehicle's payload capacity, but to remove overload springs and substitute airbags should not lower your weight capacity. Most airbag systems are rated to 5000lbs.

R4Tech systems do just this, remove the stiff leaf springs and substitute air bags with no loss of capacity. Kelderman's 4 link system removes the leaf springs completely.
