Take your mud riding performance to the next level with the EPI Performance Mudder Clutch Kit engineered for the 2024–2025 Polaris RZR XP 1000 and RZR XP 4 1000. Designed specifically for machines running 30 inch or larger mud tires, this clutch kit helps restore lost power and deliver the low-end torque required to conquer thick mud and demanding terrain.

The EPI Mudder Clutch Kit recalibrates your CVT clutch system to improve torque delivery, reduce belt slip, and maintain proper engine RPM under heavy loads. Designed for riders operating at 0–3000 feet elevation, this kit helps ensure consistent performance in muddy and challenging riding environments.

Why Upgrade to an EPI Mudder Clutch Kit?
Stock clutch systems are not designed for the extreme demands of mud riding and oversized tires. Without proper clutch tuning, you may experience reduced acceleration, belt overheating, and excessive clutch wear. The EPI Mudder Clutch Kit corrects these issues by optimizing clutch engagement and restoring efficient power transfer to the wheels.
With improved torque, faster throttle response, and reduced belt slip, this clutch kit allows your Polaris RZR XP 1000 to perform reliably in deep mud and aggressive off-road riding conditions.
