EPI Performance Mudder Clutch Kit for 2008–2009 Polaris Sportsman EFI 4×4 (EBS) – 28+ Inch Tires – WE436266
The EPI Performance WE436266 Mudder Clutch Kit is designed to improve the performance of 2008–2009 Polaris Sportsman EFI 4×4 models equipped with Engine Braking System (EBS) and running oversized 28-inch or larger mud tires. Larger tires increase drivetrain load and can reduce acceleration and throttle response. This clutch kit recalibrates the ATV’s CVT system to restore lost power and ensure smoother performance when riding in mud and challenging off-road terrain.
Specifically engineered for low elevation riding between 0–3000 feet, the Mudder Clutch Kit improves low-end torque and overall pulling power while allowing the ATV to turn larger tires more easily in deep mud conditions. It also delivers quicker clutch backshift, which results in sharper and more responsive throttle control.
In addition to performance improvements, the kit helps reduce belt slip and minimize clutch heat buildup. This improves drivetrain efficiency and helps extend the life of your ATV’s drive belt, making it a reliable upgrade for riders who regularly tackle muddy trails and extreme terrain.
