I was gonna order the update kit from Arctic Cat and was wondering if anyone who has the factory blocks has ever broken them. I have a buddy who has an 02 600 C.C. and has broken 2 sets of them, and now he just rides without any, because his dealer wouldn't warranty him new ones if he broke another set. We both ride hard which im sure it the reason they keep breaking, and is why I have not ordered a set yet. I was just wondering if anyone else who rides aggressive was breaking them too.
