EPI Performance Mudder Clutch Kit for 2014 Polaris RZR 1000 XP/ 4 – 30+ Tires – WE437163 Inch

EPI Mudder Clutch Kit for 2014 Polaris RZR 1000 XP / XP 4 – WE437163

Conquer deep mud with confidence using the EPI Performance WE437163 Mudder Clutch Kit for the 2014 Polaris RZR 1000 XP and RZR XP 4. Specifically engineered for machines running 30” and larger tires at 0–3000 feet elevation, this heavy-duty CVT tuning kit restores lost power, improves torque delivery, and enhances throttle response in extreme mud conditions.

Oversized mud tires dramatically increase rotating mass and drivetrain load. Without proper clutch calibration, your RZR can feel sluggish, struggle to turn larger tires, and generate excessive belt heat. This Mudder Clutch Kit recalibrates clutch engagement and backshift characteristics to maintain optimal RPM and improve overall drivability in thick terrain.

Key Features

• Designed for 30”+ Tires – Optimized for oversized mud tire setups.
• Low Elevation Calibration (0–3000 ft) – Precision tuned for low-altitude performance.
• Restores Lost Power – Compensates for added rotating mass from larger tires.
• Easier Turning in Mud – Improves control and responsiveness in heavy terrain.
• Improved Low-End Torque – Stronger launch power under extreme load.
• Quicker Backshift – Delivers crisp throttle response during acceleration.
• Reduced Belt Slip – Minimizes clutch heat and extends belt life.
• Heavy-Duty Mud Performance – Built for aggressive off-road use.
