EPI Performance High Elevation Sport Utility Clutch Kit for Polaris Sportsman 800 EFI (2008–2009) – WE436259
The EPI Performance WE436259 High Elevation Sport Utility Clutch Kit is engineered to restore power and improve performance for the 2008–2009 Polaris Sportsman 800 EFI running oversized 27–28 inch tires at elevations between 3,000 and 6,000 feet. Adding larger tires and riding at higher elevations can significantly reduce power and throttle responsiveness, but this clutch kit recalibrates your ATV’s CVT system to compensate for those losses. The result is stronger low-end torque, improved midrange acceleration, and smoother power delivery for both work and recreational riding.
Designed as one of EPI’s most versatile clutch tuning kits, the Sport Utility Clutch Kit enhances clutch engagement and improves backshift performance, giving riders quicker throttle response when accelerating or climbing terrain. By reducing belt slip and minimizing clutch heat buildup, it also helps extend drive belt life and improve overall drivetrain efficiency.
