Arctic Cat issues 2008 sled tech updates

Cat machines get plenty of upgrades over last year's models
Published: October 27, 2007
We got an entire 200 slide presentation from Arctic Cat recently in the mail, but thought it might be easier for our readers if we consolidated only the most important info and categorized it by sled model. So, if you've got a 2007 sled and want to know what the upgrades were for the 2008 machines, you can find your sled below.
