For Those of you wondering if it would work......

Here are some pics of my 07' FX with a 14x121x1.75 Sno-x track from an 04' Pro-Xr 440. The pitch is the same and it will all bolt right up. I actually mounted the track back in October, but haven't had a chance to get it all back together and out for a test until today.. Took it for a test ride and all works 100%. For those of you who ride in deeper snow or ditches, it is a different sled! With some tweaking of the clutching (I think raising the engagement rpm will make the sled pull hard from the crack of the throttle) and track tension adjustments, this thing will be a terror in the ditches! To everyone looking for maximum loose snow traction, you have another option! Frank R

How much clearance do you have between the track and the front of the tunnel?

Crow,
I haven't measured that. If you would like, I can do that for you. Pm me and let me know. Frank.

I would think there would be enough room. They run a 2" track on the mountain sleds. I don't know if they build them any different.

wow and here I thought I was the only one who did that mod yes this track rock's and make;s the lil phazer a whole new animal, like stated B4 a lil clutch work and it'll will be a rocket on the trails/ditches I just put about 200 miles on mine this past friday riding tug hill area and it performed flawlessly. I'm still debating on weahter or not to stud it though, that's alot of weight in studs 1.83"

The mountain lites run 8 tooth drivers compared to 9 tooth on the shorties.
