"Many shock absorbers contain pressurized nitrogen gas in them as well as the hydraulic oil. If a shock has to react very rapidly to an up and down motion the hydraulic oil can start to foam. This foam causes the shock to lose some of its control. The purpose of the gas in the shock is to keep the oil under pressure so it is less likely to foam. This is the same reason a can of soda that has been shaken is still a liquid until you pop the top. The foam doesn’t start until the pressure is released."

I have gas only shocks for my 63 beetle, but they are called air sleeves and require pressurised air to be pumped via a compressor into the sleeve which makes the car go up and down in height. The air in this case is the only form of damping as it is compressed.
Other gas shocks as mentioned above will be oil and gas, not just gas.

The other possibility is the bump stop is destroyed, through age and heat cycling. What's left of the stop, forms a seal around the base of the cartridge. Then, as the damper goes up and down, it sucks out the oil, like a pump.

Took me a while and lots of money to realise that there is too much over priced sh!te being sold by ‘traders’ unfortunately.
”sorry mate, parts are used, can’t help you”
Just my experience.
I only by new parts now unless I can fully test the bits I’m interested in, funny how people change when you start asking questions
good luck.

hahahahahaha. No such thing as a purely gas filled shock. The trader is a tool. The shock will be oil filled and gas assisted.
