Yeah wtf. I couldn't slip them on for the life of me. Lubed them up, added heat and everything. The eyelets are ever so slightly smaller than the stock spacers. Since I didn't want to force them on and have them get stuck on there, I took the dremel and sanded down the inside of the 2 top back eyelets that rest on the shoulder of the bolt. Kinda messed up that I had to do that imo...
I'm using the X-evols and am running 30#in both chambers and the rebound at 6 and compression at 8 and high speed at 2turns
You are only running 30psi in the evol chamber? Seems really low? From the factory new, mine were set at 140psi in the evol chamber and 55psi in the main chamber with the rebound set at 11 clicks back from full clockwise tight. Seems pretty good just jumping around on it in the garage but that won't tell me much.
What ride height are you guys at? From fully extended to when I get on and jump around on the machine, my ride height drops about 1.125".
Is everyone running these with the reservoir on the bottom, is it possible to run them with it on top?
30 Psi is way too low, this will make the sled into a stink bug. You are going to want to start around 65 in the main and 180 in the Evol, make small adjustments from there. Remeber to lift the skis of the ground when making adjustments!
CO 2.0 I will for sure. I was told they have to be chamber down on the front but the chamber is on the top on my KMOD rear?? http://www.kmodsnowmobileparts.com/ARCTIC_CAT.php
I am confused now
On Evol type shocks (including Evol X), you typically want the Evol chamber to be higher then main chamber air pressure. Remember the Evol chambers primary job is to help control bottom out. The main chamber air pressure controls ride height, and 60-80% of normal riding.
For most riders a main chamber air pressure in the the 45- 65 psi is the norm and 85-125 for the Evol.
Some of your top pro snocross racers usually do not use more then 170 in the Evol chamber on 100 foot gap jumps.
Rebound adjustment can also have a minor effect on compression dampening.
On our website we have a down loadable air spring pressure chart for basic recommendations. That is www.tomssnowmobile.com It is under Fox focus located at the top, scroll down to "Fox Shox tech center".
The reason you are having trouble installing the new R shocks on the Arctic Cat, is mostly due to production tolerances on the diameter of the bolt from OEM. It appears Cat may be migrating toward a larger diameter bolt to help standardize that bolt. Fox can address that issue as soon as Cat determines the final bolt size. Until then you may need to slightly modify your sleeves to fit the bolt. Test fitting the sleeve before trying to install the shock will save some time. The best bet would be to drill the sleeve if it needed to be enlarged.

Great info Tom, thanks.
Klimbing, are you gonna keep that orientation of the mounting? It has its good and bads. Good is that the shock body isn't low so it won't get knicked as easily from low lying debris. Bad is that the evol chamber sits low and gets hit by debris. Hmm, not sure which orientation would be the most "safe" for the shock...
They are going to stay where they are for now....... as I don't think I can get them off without damaging something. They are on really really tight
