I just bought a bike with this shock in the rear and the frame will not accommodate a coil shock. I'm a 280lb rider and was wondering if this shock can be pumped up to higher than 300 psi?

I know Fox will never say that you can, but I am wondering if anyone has done this? What this risks are of doing this? If anyone has enough knowledge about the internals/build that they could give me an educated guess on what the max is with moderate risk of blowing o-rings?

Can't answer your question directly but have you tried volume spacers to prevent bottoming out without exceeding the rated pressure?

 

[BigMothaHucker]

I haven't yet, honestly I haven't even got the bike yet. I ordered it last week and just am trying to do a little research because I know it might be an issue...especially the way I ride. I have seen info on volume spacers and that might be an option.

I was told by someone at a local bike shop that increasing air pressure above the max of 300 is safe on that shock, but I wanted to seek out some more opinions on the matter.

Not sure if it was related to pressure in general or an isolated incident, but there was a guy in the Vorsprung Corset thread that went over 300 and immediately blew a seal while riding. That so far has been the only thing in recent memory of someone posting about issues with higher pressures in the float X

if it takes the float X how can it not take a coil?

Volume spacers work by increasing pressure as the shock compresses. So no difference there.

This is why the Float X fits but a coil shock won't.

If I do go higher is my only risk blowing out the O-rings on the air can/body seal?

Not what I wanted to hear...But thanks. I'll take note of that. Where in Idaho you at?

did you not try the bike before you got it ino rder to see if you could safely run the shock?

Actually I did not. However I did get to sit on a bike with the same size frame and it is the best one that fits me. I am 6 foot 9 and there is not a lot of options for frame sizes. If I have to I will lose another 50 pounds. This bike fits me that well.

a fox coil is 36mm ID so probably about 44-46mm OD

if you pump it up to 300psi are you getting OK sag but bottoming out too much?

try some volume reducers and if that doesnt work give PUSH a phone and see what they recomend.

for what it's worth, the manual for the 2016 Float X says max pressure if you have the EVOL can is 350 psi, I know you don't have the EVOL can, but it seems to imply that minus the can, the shock can handle 350 psi
