EPI High Elevation Sport Utility Clutch Kit for Polaris RZR S / Trail S – WE437353
Upgrade your 2016–2023 Polaris RZR S Trail S Premium / Trail S Ultimate and 2016–2020 Polaris RZR S 4 60” with the EPI Performance High Elevation Sport Utility Clutch Kit. Specifically engineered for machines running stock tires at elevations between 3,000–6,000 feet, this precision CVT tuning kit restores lost power at altitude while improving throttle response and torque delivery.
Higher elevations reduce engine output due to thinner air, often resulting in sluggish acceleration and reduced drivability. This EPI clutch kit recalibrates clutch engagement and backshift characteristics to maintain optimal RPM under load, delivering stronger low-end power and smoother midrange acceleration for both recreational and utility use.

Why Upgrade for High Elevation Riding?
At 3,000 feet and above, engines naturally lose horsepower, impacting acceleration and overall performance. The EPI WE437353 Sport Utility Clutch Kit recalibrates your CVT system to compensate for altitude-related power loss while maintaining efficient belt operation.
The result is stronger acceleration, smoother engagement, improved torque transfer, and enhanced long-term reliability — making it a smart upgrade for RZR S and Trail S owners who ride in mountainous terrain.
