It made sense to use a 4-post primary clutch for the higher-torque applications. Having four flyweights and towers would make the clutch stronger, and each flyweight could be lighter to provide the same amount of belt squeeze. So, Arctic Cat fitted their Jaguars and F-1000s with a 4-post primary last season.

Not this year. Arctic engineers have deemed they will be able to provide “improved clutch calibrations” by returning to the 3-post primary. While this will require a change in flyweight mass (each flyweight will be heavier) to make up for one less flyweight, the F-1000 also gets a 46/40 helix in the secondary for improved acceleration and performance.
