Need a someone to fill your shocks with Nitrogen?

For all those who run Rebuild-able/Rechargeable shocks like the Bilstien, Fox or King, and need a place to fill or pre-charge your shocks, I got you covered. Since I decided to go with the T-R :D ex type suspension, and buy the Fox Pro series shocks, I also decided to go ahead and invest in a Nitrogen fill station. If you have a need for Nitrogen, weather it be for your trucks shocks, ATVs or Motorcycles shocks, I can help you out. I got to looking around in my area, and no one wanted to bother with it, not even the local motorcycle dealer, unless of-coarse I bought some shocks from him. I even checked with the tire dealers who now mostly offer Nitrogen Inflation, but they were not set-up to offer the high pressures a shock demands. So I did what I want to do all along, I bought what I needed to do it myself. :D
 
nitrogen fill

According to costco (taken with a grain of salt) they are offering nitrogen fills for their tires now. They are saying that nitrogen has a larger molicuel (sp) and will stay at pressure longer because the tire will not leak as much as plain old air. the upside to this is better tire life and better safety because the tire will be properly inflated for a longer time. They also say that because the nitrogen is dry, there won't be any corrosion on todays alloy wheels.

Something to think about I guess, there's always a way to make more $$ at the tire shops!!!

They are charging an extra $2. 00 per tire to do the fill at install. So only time will tell if it's a realistic gain.

Any chemist's out there to confirm what they claim?
 
They have been using Nitrogen to fill tires in racing for the last 5 or so years. It is being marketed by several tire discounters as a better way to inflate then the traditional compressed air. While most people don't know the difference, they do recognize that they use Nitrogen in NASCAR, so it makes for a very good promotional item. They have something to Bragg about to their neighbors or co-workers.

The benefits of using Nitrogen in the racing world is for consistency. Compressed air has alot of moisture in it, when H2O or water is heated it expands, cooled it contracts. That very function is what Nitrogen counter acts. Nitrogen by nature has an affinity for water, the phone companies and fiber optic people use it every day to keep moisture out of their lines, so they can keep a clear and clean signal. in racing, they use Nitrogen in the tires so they say at the pressures they want. Put moist air in a tire and as it heats up, the pressure increases. Now this is nothing new, you heat a gas and it will expand, only by using Nitrogen they know exactly how much that expansion will be. The compressed air is ever changing, and so is it's moisture content, hence you have a rate of expansion that is not known.

In the everyday world, I don't think it matters if I have air or Nitrogen in my truck tires, but in the competitive world of racing, yes they have to use it.

Nitrogen is used in racing shocks to pressurize the oil. Raise the pressure and you raise the boiling point. Since it is moisture free, it also allows the oil to remain moisture free. As most know, water and oil do not mix or so the saying goes. What it Will do Thu is cause the oil to foam, and since oil can not be compressed and foam can be. Foam in your shocks will change the way the shock perform, just like if you were to change the valving.
 
We used nitrogen in our motorcycle tires when I was road racing back in the 80's. y-knot's correct in that the primary reason we used it was for consistency in pressure between cold and hot tires.

I agree, it's funny how people that don't know why will still pay to be able to say "I have that, it's better!"

Actually, the pressure is used to keep the oil from foaming. There is a seperator piston between the oil and the gas. Take a look here for an exploded view of a gas charged shock. If it wasn't pressurized, the oil would cavatate as it was forced through the piston and valving. Like you said, nitrogen is used because it is dry and won't corrode the inside of the shock body.



The new Fox "Float" snowmobile shocks use compressed air as the spring. They even give you a compressor to adjust the "spring rate" with. I've heard they work well for Sno-X but not for ice racing.



A few years ago, the ice scrapers on the shock rods didn't work very well, Fox was the worst because they had really poor seals. Racing on a wet track in below zero temps made for some interesting shock valving after 100 miles! The fresh oil I had just put in looked like slush coming out.



I've been thinking about building a pair of shocks for the front of my truck. Yeah, right after I finish my other 3,861 projects.

Have you recieved the trex suspension yet? If so how is installation? Can't decide between the Fox or Bilstein. Money wise i want to go with the Bilstein but might regret it later not going with the FOX right off the bat.



Let me know how hou like it.
 
On a similar note, I now have a nitrogen charging system for filing shocks for anyone in the Monterey Bay, Calif. area. Just send me a personal e-mail.
 
Jared They are easy to put together. All you need is a high pressure nitrogen regulator(600 psi 2nd stage) a shut off valve amd a high pressure hose adapted to a Schrader valve filler. Got most parts at a welding supply, and the Schrader fitting at a truck supply. And of course a nitrogen tank! Easy but cost is over $300 unless you can find used. None of the 4x4 shops in my area have bothered yet. Many underfill the shocks only to 125 psi, this will not give good performance, you need 150 for Kings and 200 for Fox, they will cavitate at lower pressures.

Go with the kings you will love them Oo. Oo.

I sure do :D

They are hand made and will stand behind them Oo.

You get what you pay for :-laf

You can buy them from king and save some money Oo.

Good luck

I have all the parts in house, just don't know when I'll make the switch. Kind of funny that while I was responding to this post the UPS guy comes and delivers the shocks. They look very nice and did come with the reservoir mounts. There is nothing to the installation, just replace the shocks and depending on how you go, replace a few other items. I am not going with the Mini packs, I already have a set-up that has no overload spring packs and air bags, and I like the way it works. Also, I will not be using the aluminum front shock mount, I will instead use a dual shock mount from Fabtech and run dual Fox front shocks. Yes 6 Fox shocks are expensive but I wanted to try something different.



Glade to see so many people take an proactive stance with regard to the Nitrogen availability problem. Like mentioned before, to set yourself up it requires that your buy an Nitrogen (580) regulator, hose,fill end and a tank to store the Nitrogen. The cost are around 300 or so. On the regulator,I choose to go with a 0-400 secondary pressure gage. I also plan on experimenting with different pressure levels, just to see the difference.

I went by the Costco in Sequim, WA on Friday to get a tire valve replaced and noticed a big NITROGEN sign on their air tank. The system looked to have a number of components, so I'm wondering if it's not a nitrogen generator? The goof ball working on my tire swears it's better than sliced bread! I wish Costco had put the money into a better balancing machine or better training since it took a second trip back and 30 minutes on the balance machine to get the balance fixed on the tire they repaired.
 
I have found out in my area alot of tire shops don't use nitrogen anymore, (not sure why). I had to take my steering stabilizer to a local 4wheelparts to get it refilled.
