Has anyone seen this happen before? I was installing new hy-fax on my 2014 RMK assault and this time opted to use the Polaris factory black ones VS the white ones. On the first hy-fax there was a gob of plastic in the end that slides on the skid first so I went to trim it out with a knife and this is what happened to the end. So i grabbed the second one and was going to put it on and started in on the skid and tapped the end to slide it on and the edges exploded right off the hy-fax. Not sure, maybe this is a factory problem, not like I beat them with a hammer it was just a simple tap like I always do to install.
