Thicker than the OEM limit washer which limits the clutch shift. While this will limit your top speed more than factory, we found this to drastically help belt life and clutch longevity. This is because the belt does not come as far out of the primary clutch, giving it more surface area to grab. Because we limit the primary, it also prevents over shifting of the secondary clutch and bottoming out on the center of the clutch, which creates a ton of heat.
Speed limitation depends on tire size and gearing of your RZR, but will be roughly 85mph on stock tires
Does not effect primary spring rate, so your engagement will stay right as it is, and your peak RPM will not change.
A must have for those riding at 60+ MPH often
Centers the spring better for more consistent clutch performance
Machined from Delrin which helps prevent spring bind
