Kenworth 8 airbag question

[W9L]

Hate to hijack but I am planning on replacing most or all 8 on my 93 W900L 8 bag pretty soon. And all the little cast plates between bag and frame. I have heard for years that if you go to bigger air lines feeding the bags that it improves stability and ride. The later trucks seem to come equipped this way oem. Does it require a different air bag to accept a larger npt fitting or do people use reducers. I would think reducers would create a bottleneck and negate a lot of the improvement?
