Looks like the IFP seal has gone in my 2010 RP23 Boost Valve, 200×57. Perfectly happy/able to sort it myself and it’s just sitting in the spares box doing nothing anyway. Problem is, Fox are very tight lipped about this sort of stuff, cos they want you to pay them to fix it. So I can’t find the measurement I need. I’ve got the measurements for the pre-boost valve shocks, but don’t know if they are the same. The pressure in the IFP chamber is different in the BV version, so wondering if the depth would be different too?

Other option would be to measure the depth before removing it. The damper oil isn’t leaking so, in theory, the IFP should still be at the correct height. Would rather be sure what the measurement is before I strip it down, just to be on the safe side.
