The patented dual-quadrant HeelClicker flyweight optimizes the belt squeezing forces within the contraints of space established by the Polaris-factory outer clutch cover around the primary clutch. Our flyweight has a second mass attached to it (officially called a “shoulder”, but some may casually refer to it as a second “arm”) that is located such that it applies more force to the clutch/belt during operation without compromising your WOT speed.

Polaris significantly reduced the space we need for our technology when they came out with their new 2015 “High Flow” cover. Not all 2015 models come with it automatically and it can be optionally installed on a machine that didn’t come with it.

In order for our weight to fit in the newer style cover, we are designing a spacer to “bump out” the cover to create the clearance our HeelClicker flyweight requires. If you try to run our flyweight in this cover without the spacer, it will wear a hole (i.e., make its own clearance) in your cover. Prior year covers (Polaris P/N’s 2634179 and 2634160) do not have this issue if they are centered properly around the primary clutch on your machine.
