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...
Mine are T'd together and Schrader valve is under the bumper. Run them at 15 psi when empty and 60 when towing. I inflate/deflate them at the same time I do the rear tires.
