Again thats its purpose. But why did the other guy pull in the reference. I completely understand WHY it is needed but the reference still makes no sense.
I meantioned seals and he mentions my tires? The line of thought doesn't apply. You wanted to know about shocks and he mentioned tires. oh well looks like this is a gigantic line of miscommunication. I am out. My response is above. There are other people here who likely know the principle of nitro in air shocks better than I do. I still remember there being a leakage issue in the seal of the shock but couldn't find the reference I was looking for.
