Gas shock usually refer to monotube shock absorber (due to pressurized gas 2-3x of atmospheric pressure used in the chamber), he basically suggest you to get a good branded coilover set. LOL

Although most normal econobox car stock stock is twintube, whereas monoshock is more common on aftermarket. Both monotube/twintube can be good, we have good coilover set with twintube as well.

KW V3 is one of them.

Lol. In my world those are called "shock".

If someone specifically say "gas shock", it automatically refer to monotube.
