I put the Hunterworks belt on also and haven't seen anymore rub.The machine we have is a 2020 XP2. After the Polaris clutch fix it still had the case rub. I put a Hunterworks belt on instead of the Polaris belt and it does not rub. Not sure if it is a wider belt or slightly shorter, but like I said, it does not rub anymore. Now our backup belt is the more expensive Polaris belt.
