In the new 2010 accessory book it shows the regular skidplates plus a Black HD one it calls it with a price tag of about $50 more then the rest. I asked at the Arctic Cat booth at haydays and got nothing but a blank look followed by the answer it must be heavier. What i'm wonder is it just thicker or does it cover more area like the Fseries one it shows a picture of in the catalog. If anyone has any info or has an idea were I can find out I would appreciate it.
