EPI Performance High Elevation Sport Utility Clutch Kit for 2008–2009 Polaris Sportsman 500 EFI – 27–28 Inch Tires – WE436261
The EPI Performance WE436261 High Elevation Sport Utility Clutch Kit is designed to optimize the performance of the 2008–2009 Polaris Sportsman 500 EFI equipped with 27–28 inch tires when riding at elevations between 3,000 and 6,000 feet. Oversized tires combined with high elevation riding conditions can cause noticeable power loss and slower throttle response. This clutch kit recalibrates the ATV’s CVT clutch system to restore lost performance and improve overall power delivery.
As one of EPI’s most versatile clutch tuning kits, the Sport Utility Clutch Kit improves low-end torque and midrange acceleration while providing quicker clutch backshift for crisp and responsive throttle control. Whether you’re trail riding, tackling occasional mud or sand, or performing demanding tasks like plowing and hauling, this clutch kit helps your Polaris Sportsman deliver smooth and reliable performance.
The WE436261 clutch kit also helps reduce belt slip and minimize clutch heat buildup, improving CVT efficiency and extending the life of your ATV’s drive belt. It’s an ideal upgrade for riders who run larger tires and operate their ATV in higher elevation environments.
