Polaris Sportsman 800 EFI Clutch Kit for 27–28 Inch Tires – EPI Performance WE435073
The EPI Performance Low Elevation Sport Utility Clutch Kit (WE435073) is engineered to restore performance and improve throttle response on the 2005–2006 Polaris Sportsman 800 EFI running oversized 27–28 inch tires. Installing larger tires can cause power loss, sluggish acceleration, and increased clutch wear. This precision-tuned clutch kit recalibrates your ATV’s clutch system to compensate for the added rotational weight of larger tires, helping your machine deliver smoother and more responsive performance.
Designed for riders operating at elevations between 0 and 3,000 feet, this sport utility clutch kit provides stronger low-end torque, improved midrange acceleration, and faster clutch backshift. The result is crisp throttle response and more efficient power transfer across a wide range of riding conditions. Whether you’re trail riding, tackling occasional mud or sand, or using your ATV for plowing and hauling, this clutch kit ensures dependable performance and reduced drivetrain strain.
