On some of the Polaris sleds, there were aftermarket brackets that gave additional bracing above the hoop. There are also after-market steering columns made of stouter material. Some steering columns are hollow at the top. I have read about putting additional bracing inside the column to strengthen it. Some guys have even cut the top of the column off, added bracing, then rewelded the top.
When I had an Edge RMK, I did the first; added a bracket with an additional bearing above the hoop. It worked awesome, but the company that sold those no longer sells 'em. I have a Rox 5" on my 700 and am sometimes nervous because I have not done anything extra to strengthen the column.
I'm definitely not a Ski-doo guy, and only ride with one guy that rides one (a Summit 1000), so I don't see a lot of broken ones. But with 9" of rise, that's a ton of leverage to be adding, so it would be a good idea to ask around and see how well the steering column handles the additional torque. Just my humble opinion
