this seems to be the only aftermarket belt for the can ams that resembles the beefiness of the oem belt. would be great to see someone try it out and give their impressions, both initially and long term. every other aftermarket belt has failed miserably, from what i've read. however, they all (up until this one) have been considerably smaller/thinner in appearance to the oem. there's not a huge difference in price between the EPI severe duty and oem, but availability may make the aftermarket belt popular, if the oem is on backorder.
