Airmatic Conversion - Has anyone used this kit

However, it makes very little sense to me personally to convert to non-air suspension when you loose a lot of the robust ride capability, changing suspension settings, auto-leveling, etc. Your best bet and even cheaper bet is to get Arnott Industries air suspension parts that are lifetime warranty - an even better ride that OEM air parts, easier install, and all of the functionality you need with the peace of mind of a lifetime component. Changing out rear control arms is very expensive in most cases so it doesn't seem like the best solution in my opinion. I'm sure you have your reasons though, so go ahead and use that search bar
