Yea I was thinking the same thing. I think that is why there is a stud picture on the track with a slash thru it. "so stud picture". I don't want to scare anyone. I haven't heard that many reports of them comin' apart, just a few. google it and you will see what they are saying. Also you will notice these were on a lot of turboed and boosted sleds. Like I said, it ain't gunna stop me from getting another one unless this one was to blow apart. As far as price there is a place called snow city. It is out there at the Bronson snowmobile auction and I bought mine there for less then $500 o.t.d. I could not have bought a rip saw and studded it for that. I also have heard different story's on the design. Some say it is a rip saw some say it is based on a rip saw design. I don't know, all I know is it hooks up way good for me. In the corners, no push. Out of the corners, rockets out. On the road, no wash....
