Polaris Sportsman 500 EFI 4×4 Clutch Kit for 27–28 Inch Tires – Low Elevation | EPI Performance WE43050
The EPI Performance Low Elevation Sport Utility Clutch Kit (WE43050) is designed to restore lost power and improve throttle response for the 2006 Polaris Sportsman 500 EFI 4×4 with EBS running oversized 27–28 inch tires. Larger tires increase rotational mass and drivetrain resistance, often causing slower acceleration and reduced throttle responsiveness. This precision-engineered clutch kit recalibrates your ATV’s clutch system to compensate for the added load created by oversized tires.
Optimized for elevations between 0 and 3,000 feet, this sport utility clutch kit improves overall power delivery by increasing low-end torque and midrange acceleration. It also provides quicker clutch backshift, resulting in crisp throttle response and smoother power transfer during demanding riding conditions.
Whether you’re trail riding, tackling occasional mud or sand, or using your ATV for work such as plowing and hauling, this clutch kit helps maintain reliable performance while reducing belt slip and clutch heat. The result is improved drivetrain efficiency and longer belt life.
