Fox Bumpstop Issue

[chevydude7]

I have a 2015 Wrangler Sport 4 dr and i've been using Fox 2.0 IFP bumpstops for roughly 4 months (2,000 miles +/-) and I just noticed that my right front bumpstop is stuck halfway. Has anyone else had this problem? Any suggestions would be great appreciated!

Have you checked the Nitro charge pressure?

Not yet, don't have a gauge. I'm assuming that's more than likely the culprit! Thanks for the response!

I believe that the 2.0 bump stop has a negative spring internally, at least they used to. When they loose the charge, they go to half staff.

@Mark Newhan You are correct about the negative spring! Thanks for being able to pinpoint the problem! Do you think it's from a bad seal or are they prone to losing nitrogen over time? I sincerely appreciate your help.

I'm sure it was from the air valve. If it was from the seal, you'd see oil. If the air valve has only the small chrome cap, make sure the little red rubber "oring" (it's not really and oring, more like a doughnut) is in the cap and not where it can depress the needle valve.
