2014-2015 style Big Fin clutch provides the highest rate of improvement on 2012-2013 models
Arctic Cat's testing showed the Big Fin clutch resulted in twice the durability
Has upgraded high-temp DuPont bearings in the cam and movable sheave
DuPont bearings withstand higher temperatures, making the clutch more free moving and less binding
Binding in a driven clutch hampers the shift pattern, resulting in pulling the belt apart
Added height to the fins, pumps more hot air out of the clutch compartment, allowing more cool air in
The larger fins keep the belt and clutches operating up to 30% cooler
When installing this clutch the offset will need to be checked, and corrected if necessary, with an alignment bar (sold separately)
Includes one assembled 0726-342 clutch with 42/40-helix (0748-772), 202-284-lb blue spring (0648-813), and installation instructions
