Default Looking for 2012 SBA High Elevation Clutch Parts?

Taking my sled to the Snowy's in March, I changed to a 2" track the factory 2" gearing, looking to see if anybody has the clutching for high elevation that they are parting with.

Thanks

Go with 10-60 weights and 20/43 gears. SLP recomended springs. I ran the Snowys in December like this. BELT stayed cool.

What elevation you gonna be running at? I ran 6 - 8k and ran the slp blue pink with 10-64 stock helix with black purple spring and ran real well. Another guy with same sled had 10-60 and mine ran way better. Best advice is run what the rmk runs at your elevation

I ran 8k-12K in Wyoming on my set-up and it was killing the pther Assaults that had only different springs/weifgts and not the gearing. Polaris recomended 20/42 so going 43 added a lil more and you can feel it. Motor never felt bogged and the belts stayed COOL!!!! (till parking brake was set and i tried to drive down hill). Roll your handle bars back also as it'll help you sidehill. My first ride I had them straight up sno-cross style which was nice on the trail, but I couldn't side hill worth a crap, as it pulled me out over the sled.

I've always found the SLP techs very helpful in helping pick weight for elevations. Give them a shout or email them if your interested. Included the stock clutching info for ya too.

Well I ended up with the following set up, leave Friday and can't wait!
10-60 Weights
SLP Blue/Pink Spring
RMK Helix
Black/Purple Spring
144x2 Challenger
I don't remember what I changed the gears to when I did the track swap, whatever the 2" model comes with.

How far back are you pulling them back?

Also, did anybody mount the front of the skid in a different hole?

Dont touch the skid holes!!!! And ive rode w and w/out sway bar. Prefere the sway bar as our shock ie springs are setup to have it. Roll bars back to the 1 or way back to the 2 line.

depending on rider size i ran my bars straight with the post (idk numbers) suspension set soft on the clickers. clutching was exactly what polaris reccomends for 10-12k elevation. except i would have liked to keep my stock primary spring in. engagement was too high and it wanted to trench, 10-58 weights worked good with the snow and stock gearing and helix were great. I would listen to buddys doo 800s and they found lug down on a hard climb..mine would hold the RPMs. i just got back yesterday and the snow was set up and sticky first part of trip and got fresh last few days. When the suspension was still stiff from U.P riding it trenched ALOT. I softened it up and learned better throttle control on take off. Have fun..good luck
