What are these things pressurized with? Ive got one and it seems to have lost its charge. Its not free, meaning I CANT move it in and out easily. Its just stuck in one place but its not bent. I CAN move it in and out by pulling and pushing against it but its hard like its still pressurized however when I put in in or out at any length it just stays there. Any help?

it shouldn't be easy to move. they come pressurized pretty heavily, out of the box.

i'm not 100% sure, since i haven't seen one, in person, in years, but i think it is just air. no?

isn't there a valve stem on one end of the body?

i know there is someone on here that has one that will know for sure....but i'm not sure it matters what gas you put in it (except that nitrogen or CO2 would be more temperature stable).

i would guess you wouldn't want to add any. i would guess around 50-60 psi would be close to ideal.

wait for someone else to chime in here (philD and AlecW should know for sure) , but it would kinda be a trial-and-error thing with setting it to where it feels best to you, without having so much pressure it causes your jeep to drift to one side. if you find out from one of them, post it up here, please!

We'll do! Thanks again for all your help tonight. :beer:

Don't use air!
They're Nitrogen charged and should be at about 15-20PSI
It should push itself out but not ridiculously hard
they used to come way overcharged and caused steering push.
some people have been ok running at 50 PSI without push
I think mine is at about 15
the reason not to use air is temp stability and not to introduce moisture into the shock or it will corrode on the inside

Sorry, just saw this. I have 50 PSI in mine and it pushes a little. FWIW I used C02 to figure out what PSI I liked and then went to a shop to have nitrogen put in it. I "think" the only reason they suggest nitrogen is because C02 has water in it and can corrode over time from the inside.

BTW there is very little gas volume in these things. I lost all the nitrogen mine came with when I put an air pressure gauge on it too slowly, which is why I used CO2 for a while ;). Don’t try to use a compressor you may blow something, I used a fancy hand bicycle pump a friend had to put CO2 in it.

Yup, but for a different reason. Dry gases have a pretty straight linear relationship between heat and pressure, "wet" gases don't and pressure increases exponentially with heat, to a point anyway. A dry gas will be less sensitive to "pumping up" than a wet gas, which is a bad thing.

Air also contains oxygen, so you'll get corrosion.

Nitrogen is about the cheapest dry gas you can buy.

Doesn't sound right. A pressurized shock will extend back out by itself, and the Fox steering dampener most definitely will. It may have lost its gas or have a faulty seal.

bringing this thread back from dead.

I've got the Fox IPF steering stabilizer. How do I check the pressure, does the valve just take a standard tire pressure gauge?

If I want to lower or increase the pressure, how do I actually do that if I shouldn't use air to fill it...although I think I may need to bleed some out.

Best bet is to get a gauge specific for checking nitrogen. KarTek sells a great one, kinda spendy, though I have a bunch of coilovers, bumpstops and other stuff on my vehicles to check. It'll allow you to check em without losing the charge and you can air down without letting the whole charge out.
