I have Air Lift bags on my Ram, and air them up to 32 psi when pulling our TT. Empty I drop them the down to about 5psi,
I had some installation issues (winter time) and recommend that you attach the air lines before installing them into the coils. Warming with a hair dryer helps, also when they are 95% in the coil and you are ready to give up use a air pump to increase the pressure and they will slide right in (one of two reasons to attach the air lines before installing; the other being it is difficult to attach the lines after installing the bags).

When the pressure is released they have no effect on the ride or height.
