The nitrogen in shocks is not there to affect damping rates. Shocks are filled with nitrogen gas in order to eliminate cavitation (air bubble formation) in the oil as the piston moves through the oil. Air bubbles in the oil wreak havoc with the oil's damping ability.

The nitrogen gas is in a bladder which exerts pressure on the oil to keep the oil pressure high enough to stop cavitation. If you reduce the gas pressure, all that will happen is that the oil will get all frothed up and your bike will pogo around. You should keep the gas pressure at the manufacturer's recommended level. Too low and the shock doesn't work right due to air bubble formation. Too high and you risk a blow out.

Nitrogen instead of air is used because it is an inert gas and prevents degradation.

:applause: Exactly. Nitrogen does not expand or contract due to temperature change, nor does it break down over time once it's charged up. Do not mess with this level! :bonk:
