Hey, I was wondering if fox airshox come charged with the nitrogen or if I have to find some place that can do it. Thanks.

I have a bottle in my garage... I could hook u up with a fill !

then again most shops will fill them 4 u!

With the AirShox, you really neet to be able to fill them yourself. Afterall, that's how you tune the shock's spring rate. If you just fill them with...let's say 300psi, and they are too soft or too stiff, you really have no way to change then psi without a compressed nitrogen source.

So....here is what you need to do. Go to Ebay, and buy a nitrogen regulator with an outlet pressure rating up to 500psi. You can usually find the ones that people use for HVAC stuff. The closer you can get the gauge to read a range of 1-500psi, the more accurate your system will be. I got mine for $78 brand new. Then go to a welding supply store and buy/lease a nitrogen tank from them. I paid $130 for a tank with a fill. Then go to a hydrolic hose place (like Parker Hose) and have them make you a hose that will hold up under the high psi's you will be using. I had a braided stainless hose made for like $35 (10ft long). Make sure that the hose is long enough to allow for easy tuning. Then go and get a high quality air chuck from an auto parts store. Then you can set the desired pressure at the regulator, and fill the shocks like a tire.

or just call Marvin Shaw and buy the fill kit!
