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?

My prostar used to be super-reactive on the air bags... I hated it and put restriction (needle valves) at my air bags and now it rides much nicer. Until I did that, my truck felt top-heavy all the time.

- I guess some people like it smoothed out.. and some people like it super responsive. Just throwing that in there.
