Polaris Sportsman 800 EFI Clutch Kit for 27–28 Inch Tires – High Elevation | EPI Performance WE435082
The EPI Performance High Elevation Sport Utility Clutch Kit (WE435082) is designed to restore lost power and improve throttle response for the 2005–2006 Polaris Sportsman 800 EFI running oversized 27–28 inch tires. Larger tires can reduce acceleration, create sluggish throttle response, and increase drivetrain strain. This precision-engineered clutch kit recalibrates your ATV’s clutch system to compensate for the additional tire weight and rolling resistance.
Optimized for elevations between 3,000 and 6,000 feet, this performance clutch kit ensures your Polaris Sportsman maintains strong power delivery and responsive handling even at higher altitudes. Riders will experience improved low-end torque, stronger midrange acceleration, and quicker clutch backshift, resulting in crisp throttle response and smoother power transfer in demanding riding conditions.
Whether you’re trail riding, navigating occasional mud or sand, or using your ATV for plowing and hauling, this sport utility clutch kit helps your machine perform more efficiently while reducing belt slip and clutch heat.
