MCI 9
Convoluted air springs with air frame,
Air moves from air bag to steel box frame and back creating a softer ride.
If frame leaks bus leans.
By plating the top of the bag and filling air at top you can bypass the Air Beam
.
However, You must make sure you use the correct air bag replacement or
the bus will ride like a truck .

Back to top
New style top plated air springs bypass the leak prone air frame with a
softer air bag and and creates a better ride.
If you ever plate your air suspension system don't forget to make sure you
change out to the softer air bags too
If you replace with the same air bag the bus will ride like a dump truck .
