I’d like to add airbags to my rear suspension on my Ram 2500 diesel to level my truck when I’m towing, but don’t really feel I need to be able to control them from the cab and don’t want to go through...
last set of firestones I installed came with a "T" for plumbing both bags into one air up fitting which i installed adjacent to the rear license plate.
I see no need to have them filled separately and don't subscribe to that urban legend of the air transferring from one side to the other when cornering.
