Need to charge shock to 150-160psi of Nitrogen, Where can I do this with out having to buy a bottle??

Not sending my stuff out anymore for the fact that I need to change shock fluid more frequent.

Any of you find it funny that air is used in MTB shocks/forks and in your MX front ends but nitrogen is used in your shocks?

I've done some research this morning and mis information out there is unreal.

BTW, 5 dealers around me don't do it. I'm not surprised. I was the go to guy in this area for years to build and true wheels because dealers were clueless.

Shouldn't the air in the shock be evacuated before charging with nitrogen?

mtb forks and shocks dont reach the same temperature as a dirtbike shock. Also, the air being used in mtb is for the spring, not for the bladder/ifp. Heat from the exhaust plus the higher forces bring shock temp pretty high in mx. Nitrogen doesn't raise in PSI due to temp fluctuations as much as regular air. Both work the same way besides nitrogen molecules also being larger so it also wont leak as easy. Air would work but when you shock temps go up, so will your psi. The only reason you see air being used in forks and mtb scene is because no one wants the hassle of having a nitrogen setup. Factory bike teams are using nitrogen in the spring side of forks...on a side note, i would think a welding supply/gas supply company should be able to fill your shock, just not sure how accurate their gauges are for filling that type of thing

air is 78 percent nitrogen. mtb pump works fine, if using nitrogen is an "A", mtb pump air is a "B+"

Lots of shops won't do a nitrogen charge on shocks they didn't assemble for safety reasons.

I have used tire shops in the past to do nitrogen charge, post rebuild. The only issue(s) was they wouldn't go over 145 psi. Also, if you have a Kawasaki style (needle type, not shraeder valve), then there's nothing they could do

I always used air in my shocks as long as the compressor has a good filter system on it for moisture. I usually use about 5psi less than if i used nitrogen. Never had a problem.

Many use air without any issue. I have been for several years.

Nitrogens though is the way to go as a has a quick response time and it's bends rapidly which automatically changes the bound and rebound.  As well it cools off quickly which returns it to a nice comfortable ride.

The air should be evacuated first.
