International 9400 vs 9900

[Chamberpains]

Is your ride height set properly? Is the cab suspension completely junk? International sells an entire bolt in unit to replace everything in the cab suspension. It was very reasonably priced and made the job extremely easy to do. What do your torsion bars look like? Are the bushings toast? How new are the tires? New tires made mine feel like it was swimming. My 9400i rode decent but you have to replace all that 16 year old suspension stuff. It only lasts so long before it doesn't work.
