"Gas-filled" shocks cam be compressed by hand so the pressure inside can't be more than a few PSI. It doesn't make good nonsense that the minuscule amount of extra pressure makes much difference where a vehicle weighing several thousand pounds is involved, or when considering the shock load of hitting a bump on the springs and suspension is considered. The so-called advantage of putting an inert gas in a shock is supposed to prevent the oil from foaming. P.T. Barnum was right- - - - -"There's a sucker born every minute!"
