These are necessary since there are no shutoff valved in the lines to the airbags. With instant response valves you need shutoff valves or any out of "level" on any control valve will ultimately result in an empty airbag after the engine compressor is shut down. My system works fine adjusting to weight changes and bumps without constantly floating. I don't understand what advantage there would be to instantaneous valves. Perhaps I've missed something. I did replace one failed valve with Haldex brand supplied by Newell.
