EPI Sport Utility Clutch Kit WE437821 for 2024–2025 Polaris RZR XP 1000 & XP 4 – Oversized Tires & High Elevation
Upgrade your UTV’s performance with the EPI Performance Sport Utility Clutch Kit engineered specifically for the 2024–2025 Polaris RZR XP 1000 and RZR XP 4 1000. This clutch kit is designed for riders running 30–32 inch oversized tires while operating at higher elevations up to 6000 feet, where reduced air density can significantly affect engine performance.
At higher altitudes, thinner air reduces engine efficiency and power output. Combined with oversized tires, this can lead to sluggish acceleration, poor throttle response, and increased clutch heat. The EPI clutch kit recalibrates the CVT clutch system to restore lost power, maintain proper engine RPM, and deliver smoother power transfer across a variety of terrains.
