Aftermarket Assassins RS1 Primary Clutch Limiter| 2016+ RZR Turbo
The main clutch limit washer is designed to fit models such as the 2016-2020 RZR Turbo, Turbo S, and 2018-22 RS1. However, it is not compatible with the 2021 Turbo models or the 2020-Up Pro XP/Turbo R models. This washer is thicker than the original equipment manufacturer (OEM) version, which is responsible for regulating clutch shifts. While this modification may reduce your top speed compared to the factory setup, it significantly contributes to the longevity of both the belt and the clutch.
The increased thickness of the washer limits the extent to which the belt extends out of the primary clutch, resulting in a larger contact area for improved grip. This adjustment not only curbs excessive shifting in the primary clutch but also prevents excessive contact and heat generation in the center of the clutch, a common issue. The exact reduction in speed varies based on your RZR's tire size and gearing, but it's generally around 85mph when using stock tires.
Importantly, the installation of this washer does not impact the primary spring rate, thus maintaining your existing engagement feel and peak RPM. It's an essential addition, particularly if you frequently ride at speeds exceeding 60 mph. Additionally, this washer aids in centering the spring more effectively, leading to more consistent clutch performance. Crafted from Delrin, this component helps alleviate spring binding, enhancing overall performance.
