    Vanilla RC Internal Floating Piston Depth?

    In the process of rebuilding my shock, and I need to know this before it can go back together. Anyone know?

    Contact PUSH, they might tell you. Maybe Fox would.

    Fox won't give out that kind of information. You basically screwed yourself over when you tried to work on the shock by youself. Rear shocks are not user servicable except for air sleeve rebuilds, but that doesn't apply to you in this case. The only thing you can do now is send the shock to fox for a rebuild or push if you want to get it revalved for your riding style.

    Can't bash a guy for trying. The rebuild is actually quite straight forward, if you have all the proper info. I wish I did.

    Hey shift, did you get a hold of some type of rebuild manual to take it apart or just took it apart?

    You're right, rebuilding them isn't hard at all. The only problem I have is finding the IFP depth. Neither Push or Fox will release the info which is strange because I've rebuilt many snowmobile Fox shocks and they've readily gave me the info that I asked them for. And seeing how they don't release that info, it's near impossible to search the internet to find it.

    Just a guess

    Put enough oil under the piston so it never "tops-out" which would limit full extension and suck air past the shaft seal. I imagine give it at least a 1/4 inch oil level, probably 1/2 inch before the extension limit.

    Probably set the oil level so the piston is floating about midway in the chamber at shaft full extension.

    Relatively more oil, leaving less air in the reserve, will produce a more rising rate of compression, and possibly reduce compression travel without a lighter coil spring. Too small of an air space could cause the air reserve psi to rise so much and burp past the piston into the oil.

    What kind of air valve are you fitting? I've read how the reserve air seal can be drilled out to service it yourself. When you drilled out the seal was there a scary pop of released air? Or just a small pffft? And I've heard that you need about 300 psi in the air reserve.

    This is interesting to me and something I'd like to try to do someday too.
