EPI Mudder Clutch Kit for 2017–2021 Polaris RZR 570 (EBS) Standard / Premium – 28”+ Tires (WE437667)
Turn your 2017–2021 Polaris RZR 570 (EBS) into a true mud-ready machine with the EPI Performance WE437667 Mudder Clutch Kit. Specifically engineered for models running 28-inch and larger tires at 0–3000 feet elevation, this heavy-duty CVT tuning kit restores lost power and improves throttle response under extreme drivetrain load.
Oversized 28”+ mud tires significantly increase rotating mass and resistance, often causing sluggish acceleration and excessive belt temperatures. This EPI clutch kit recalibrates clutch engagement and backshift characteristics to maintain optimal engine RPM, allowing your RZR 570 to turn larger tires more efficiently in deep mud conditions.

Why Upgrade for 28”+ Mud Tires?
Running oversized mud tires without recalibrating your clutch system can drastically reduce acceleration and increase belt wear. The EPI WE437667 Mudder Clutch Kit restores torque transfer efficiency, maintains proper operating RPM under heavy load, and enhances overall drivability.
The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved durability — making it an essential upgrade for RZR 570 owners building a serious mud machine.
