SLP clutch kits have been designed and tested to get the most consistent performance out of your Polaris UTV. We have been working with centrifugal clutches for over 40 years, and know how to tune them to transfer your horsepower to the ground. In most cases, optimizing the clutch setup is the best performance gain for the dollar spent. Through our testing we have found two distinctly different clutch setups depending on what type of terrain that you drive on.SLP Trail Clutch kit:These kits are designed for semi hard surface trails with the occasional run in muddy or sandy conditions. They provide improved engagement mannerism, throttle response with better top end power and consistency over a broad range of elevations and conditions.SLP Sand, Mud or Large Tire Clutch Kit (High Load):These clutch kits are for high load environments such as sand, mud or when 1" to 2" larger tires have been added. When exposed to these high load conditions, the stock clutching performs poorly, leaving the vehicle with poor throttle response and loss of RPM. These clutch kits provide improved engagement mannerism, throttle response with better top end power and consistency over a broad range of elevations and conditions.Note: If performance modifications, larger tires (+3" or larger), paddle tires, or weight has been added or removed from you UTV, please let us know so we can tailor your clutch kit accordingly.All clutch kits require use of Polaris OEM Belts: 2016 1000 RZR - #3211180. Using any other belt may require additional tuning from the end user.
