...I'm thinking of upgrading my track from 133x15x0.82 to 133x15x1.5. (1996 Polaris Classic Touring - don't ask why I don't have a mountain sled!) I checked for tunnel clearance & there appears to be adequate clearance for a 1.5" lug track (2" of clearance on the top of tunnel & up front by the heat exchanger), but my concern is that the 500 will have trouble turning the track in the powder.

Any thoughts or suggestions would be appreciated - thanks.

Run it and if you don't think it feels good
then gear it down you'll loose some top end is the only thing.
I put a taller paddle track on a 500 fan cooled and it hooks up alot better than the original,put a 1.25 on.
You might have to notch for the heat exchanger (not sure though)

...funny you should mention gearing, because after I posted I checked the polaris microfiche & confirmed that I'm running a 20 tooth top sprocket, which probably explains why it has pretty good low end & crappy top speed out of the crate (sled is currently stock).

As for the heat exchanger, I'm hoping that I can get away without mods, as I am predicting about 0.25 inches of clearance up front (2 inches of gap less 1.75" track thickness, far as I can tell).

Thanks for the feedback.

Both my Indy 500's have 1-1/4" tracks and there is enough clearance on mine to go 1-1/2. Mine are SKS models but have the same 133 track. Not sure what chassis yours is. Mine are the Evolved chassis

I'm running the evolved chassis with the Xtra 12 touring suspension (which I understand has the worst approach angle of all time), so it sounds like clearance shouldn't be an issue.

Thanks for your comments
