EPI Performance Mudder Clutch Kit for Polaris Sportsman 800 EFI 4×4 (2008–2009) – WE436322
The EPI Performance WE436322 Mudder Clutch Kit is specifically engineered for the 2008–2009 Polaris Sportsman 800 EFI 4×4 with Engine Braking System (EBS) running 28-inch or larger tires. Installing oversized mud tires often causes power loss, slower throttle response, and increased strain on the CVT system. This high-performance mud clutch kit recalibrates the clutch engagement to restore lost power and improve torque, allowing your ATV to handle larger tires more efficiently in demanding off-road conditions.
Designed for riders operating at elevations between 0–3000 feet, this Mudder Clutch Kit enhances low-end power and delivers faster clutch backshift for improved throttle response. Whether you’re navigating deep mud, hauling loads, or riding aggressive trails, the kit ensures smoother power delivery while reducing belt slip and minimizing clutch heat buildup. The result is improved drivetrain efficiency, longer belt life, and stronger performance when you need it most.
