Polaris Ranger 1000 Clutch Kit for 27-28” Tires High Elevation (EPI WE437604)
Restore power and improve performance at higher altitudes with the EPI Performance WE437604 Sport Utility Clutch Kit, designed for 2020–2025 Polaris Ranger 1000 models equipped with 27–28 inch tires. Tuned for elevations between 3,000–6,000 feet, this clutch kit compensates for both altitude-related power loss and the added strain of larger tires.
As elevation increases, engine efficiency drops due to reduced air density. Combined with oversized tires, this can significantly impact acceleration and throttle response. This precision-engineered clutch kit restores optimal RPM and improves power delivery, ensuring your Ranger performs reliably in demanding conditions.
