The track that was on it had that size stud. We bought the sled used and I didn't realize they were that size until I measured them yesterday. Been busy and had other things going on, should have measured them earlier. Not sure how long they have been on there but the sled has over 12000km and we've put 3500 ourselves. I will be adding that size to the middle(96) once I get the track broke in. There is no real damage whatsoever to the coolers, slight scratch here and there but no big deal. The protectors at the front are approx 3/4" thick so there's at least 1/2" of clearance. Not sure why you had that much damage, unless the track was loose or you had a bearing let go maybe the exchanger is different on the viper. Just in case I will be running the track to spec, I usually like running them a little looser.we do mainly trail riding and ditch banging,. Let's put it this way it's my 17 years old sled.
