nitrogen

[flyguy1208]

Do not want to use O2 to service the shocks during events.
What and where are you getting a nitrogen service kit from?
How often do you do you have to service the shocks to keep the pressures right?

the nitrogen kit for the top of the tank I bought years ago from amazon for about 300$.
the tank and gas I get from my area gas supply store. I bought the tank so it's an exchange when I need it refilled.
with the none upgraded shocks we charge them every morning before we would head on on track. the new upgrade kit for the shocks I have no idea how often they will need to be topped off? my plan is to check them like I was doing with the old shocks. and will see how it goes from there.

No significant pressure loss. We checked shocks the night before each track event (practice or race) and topped them up with air using a high pressure hand pump. Never had to add more than one pump. We checked pressure before going on track but never had to top up. Been sitting in a cold garage all winter and now only down 20 psi. Your mileage may vary.

Poly performance sells a kit for about 600 bux. I went to my local welding supply and bought a tank that will last you the whole yr or more

 

[paulb70]

I put roughly 6000 miles on my rush this yr. I checked them every day on track. I saw I would have to replenish them every 5 to 6 runs

Sorry, jut saw this now. I assume they are old style.

Don't forget to check/charge them before you tow!

New car. After 2 weekend events I see the shock pressures are down 100 psi every day if not more! I fill the night before and after lunch they are down to 150 to 200 psi.

That honestly might be because of the volume of your gauge.

Try measuring them again right after you’ve disconnected the pump.

If it’s not the gauge, I’d recommend getting the expanded shocks. They’re not particularly expensive and they make a difference.

If I understand how this whole shock pressure thing works (IF)

When you want to check your shock pressures, using just a pump/gauge........
Attach the line to the shock. BEFORE you open the "one-way" valve....pressurize your pump to a point just above your target value.....THEN open the "one-way" valve. If your shock is below your target value the gauge will show that pressure. If your shock is equal to or above your target value......then you have no loss and you're "good-to-go".

YMMV.
