EPI Performance High Elev. Sport Utility Clutch Kit for 2017-25 Polaris RZR S/ Trail S – 27-28 Inch Tires

2017–2025 Polaris RZR S / Trail S High Elevation Clutch Kit for 27–28” Tires (3,000–6,000 ft)

The EPI Performance High Elevation Sport Utility Clutch Kit is engineered specifically for 2017–2025 Polaris RZR S and RZR Trail S models running 27–28 inch tires at elevations between 3,000 and 6,000 feet. Larger tires increase drivetrain load, while high altitude reduces engine power due to thinner air. This precision-calibrated clutch kit compensates for both factors, restoring throttle response, torque delivery, and overall CVT efficiency—while keeping the factory Engine Braking System (EBS) intact.

Designed as EPI’s best all-around use kit, this clutch upgrade enhances low-end acceleration, strengthens midrange power, and delivers quicker backshift response. Whether you’re trail riding, navigating occasional mud or sand, plowing snow, or hauling gear, this kit ensures your RZR performs reliably in demanding mountain conditions.
