EPI Low Elevation Sport Utility Clutch Kit for 2014 Polaris RZR 1000 XP / XP 4 – WE437161
Restore performance and throttle response on your 2014 Polaris RZR 1000 XP or RZR XP 4 with the EPI Performance WE437161 Low Elevation Sport Utility Clutch Kit. Specifically engineered for machines running 30–32 inch tires at 0–3000 feet elevation, this precision CVT tuning kit compensates for the added rotating mass of oversized tires while improving overall drivability.
Larger tires can reduce acceleration, slow throttle response, and increase belt temperatures. This EPI clutch kit recalibrates clutch engagement and backshift characteristics to maintain optimal engine RPM under load — delivering stronger low-end torque and smoother midrange pull across varying terrain.

Whether you’re riding trails or using your RZR for demanding work tasks, this clutch upgrade delivers stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability.
