EPI Performance Low Elev. Sport Utility Clutch Kit for 2003-05 Polaris Sportsman 4×4 (EBS) – 27-28 Inch Tires – WE436000

Polaris Sportsman 4×4 Clutch Kit for 27–28 Inch Tires – EPI Performance WE436000

The EPI Performance Low Elevation Sport Utility Clutch Kit (WE436000) is designed to restore power and improve overall performance for the 2003–2005 Polaris Sportsman 4×4 equipped with EBS when running oversized 27–28 inch tires. Larger tires can reduce acceleration, cause sluggish throttle response, and increase clutch wear. This precision-engineered clutch tuning kit recalibrates your ATV’s clutch system to compensate for the added tire weight and rolling resistance.

Optimized for elevations between 0 and 3,000 feet, this sport utility clutch kit delivers stronger low-end torque, improved midrange acceleration, and quicker clutch backshift for a noticeably more responsive ride. Whether you’re trail riding, tackling occasional mud or sand, or using your ATV for plowing and hauling, this clutch kit helps your Polaris Sportsman perform at its best while reducing belt slip and clutch heat.
