I have a 07 Skidoo Summit 800 Last year the tunnel took a light hit and did not hold up. The dealer tryed to straighten and added stiffners but the sled still has a ski thats 2 inched off. I would like a Titanium tunnel or heavier Aluminum. The only after market ones I have seen is the carbon fiber, 8g is a little steep for my pocket. Thanks for any help you can provide.
