Air ride with 8 bagz

Older Kenworth HDT T600, T800 and W900 semi tractors used this. I think their claim was better ride because you had airbags in front and behind the axle supporting the frame, whereas in a four bag setup, the bags were only on the back side and the front was anchored solid to the frame. I had one with a grainbox and it made for whitenuckle driving as it was not meant for high center of gravity loading, so I had to run with a lot of air pressure in the bags to make them stiffer, which obviously raised the rear, thus I had to recurve the front springs to bring the front up so it rode level. Yes, more maintenance because of more fittings and potential air leaks and eventually the rubber ages and leak and bags need to be replaced, adding to the cost, but this does not happen often.
