Description

The EPI Performance Mudder Clutch Kit (WE437637) is specifically designed for Polaris RZR Pro XP and RZR Pro XP 4 models from 2020 to 2022 with 1000cc engines. This kit is optimized for off-road enthusiasts running 30"+ tires and operating at 0-3000' elevation. It addresses power loss associated with larger, aggressive mud tires by reducing belt slip and clutch heat. The kit aims to restore lost power, provide better low-end power and torque, and deliver quicker backshift for a crisp throttle response, ultimately allowing for easier turning of large tires in muddy conditions.
