What Pressure for Fox 2.5 Air Bumps?

I'm wondering what PSI everyone is running in their air Bumps? I have National Standard springs with a spare and floor jack in the bed. I'm also wondering how you go about filling them with the Nitrogen and where I can buy that.

Running about 90 psi, I believe...

I was running 75psi on my RPG bumpstop. I believe they come set at 150. Do you have the shock fill tool? Can get those from RPG.

I think I've still got mine set at that 150. RPG did come out and say to lower them down to 90 or something, but I never did do it.

I don't have the shock fill tool, but I have a high pressure gauge (think it goes to 250psi) for my Fox shocks on my mountain bike. Do I buy canisters of nitrogen?

Does it allow you to stop the flow so it does not loose ANY pressure loss? Just checking the pressure of your shocks will lower the proper psi.

Yes it does. It's made for very very expensive very small shocks to not loose any pressure. I just don't have a way to fill them up with nitrogen.

Most tire shops have nitrogen these days. But I just set up a small nitrogen tank so that I always have it and am able to maintain or change pressures
