Air shocks

[82toyota4x4]

Going to be buying the trail gear rear three link for my toyota this summer, what's the deal with filling up air shocks with nitrogen and how does that depend On the lift and is there some sort of nitrogen kit to fill em up? Haven't researched more then 30 min so don't be to rough on me haha

You need someting like this.

That is a good, easy to use kit, but VERY expensive.

You can get nitrogen from local welding shops, and a regulator as well. You can then put a simple air chuck on the end of the hose and be done. Set the fill PSI, and pop it on....regulator does it's job and it's probably less than half the price of the poly kit.

This is exactly what I did. Will need to get a hydraulic hose made to safely handle the pressure. At work they were tossing the braided stainless hose I used, so I didn't have to get the hose made.

Talked to a guy from lowrange offload and turns out the fox 2.0 air shocks come with 200 psi of nitrogen from fox, so all you have to do is dial them in from there. Sound about right ?

[ChemicalToilet]

Yeah they definitely had pressure in them when I got them. I depressurized them so I could easily compress them for set up at full bump.

Here's what he sent me

It says in order to tune them right I will need to ad nitrogen, am I wrong?

[toyoturd]

ya for rears i ran 180-220 depends on angle where they are placed on frame and axle. pm me i have a set of used fox 16's ill sell

[82toyota4x4]

I read somewhere you could add some compressed air into them for a few psi, do you think that the shocks coming with 200 psi is enough to not add any nitrogen

you most certainly should not use a simple air chuck. we are not filling bicycle tires here. getting a tank and regulator from your local welding shop is your best bet price wise. for my hose i used a hydraulic plow hose with a 90 and a swivel. i think i paid $14, works great. i think its rated somewhere around 2400 psi so it will be suffice. for a chuck it should be the no loss type like this one http://www.ebay.com/sch/i.html?_nkw=no+loss+air+chuck

good luck

I found my high pressure regulator & hose kit on eBay. Set up is designed for filling air shocks.

I have filled mine countless times with a regular air chuck. I would overshoot when filling and use the adjustment tool with the "no loss chuck" from poly performance to bleed them down to the pressure I wanted.

it seems like one extra step but if it works for you thats cool. you didnt mention that earlier so i assumed you used only the chuck. i know accuracy is pretty important.

[82toyota4x4]

found a company that will fill the pair of fox 2.0 shocks to 400 psi before shipping them to me, I thought you need to drain the completely, install them then fill them up?

[supazuk94]

if you are just gonna buy them filled and run them honestly you are not taking advantage of why you are getting air shocks .. to get the most gain you need to be able to fill them and adjust the amount of oil in them

what he said.

if your not into tuning, leafs are a good choice.

[King7765]

I really like that "no loss" fill chuck thinger...

Maybe it's the regulator I have but it's not very accurate. So I would turn it up past what I wanted then adjust with the no-loss chuck to ensure I had the same pressure in each or in my case there was a slight discrepancy to the drivers side (ie. my fat ass in the drivers seat ) so my shocks on that side have a few PSI more (about 10) to compensate.

[TBItoy]

The actual pressure number in an airshock isn't really THAT important.

you are just using it to set ride height, you might have to put more in one side to get it to set level...if you are real fat or something lol


Now in a regular shock or coilover where you are not using the air as a spring, I make sure the shocks are charged the same.
