Arctic cat update for 2013 models:
"A plastic spacer has been added to the driven clutch to improve belt life when running at high speeds on all M and XF High Country models. The spacer forces the driven clutch to reach full-shift slightly before the drive clutch can reach fullshift, thus allowing for the clutches to maintain belt squeeze at all times to minimize slippage. This spacer can retrofit to 2012 models."
