EPI Low Elevation Sand Dune Clutch Kit for 2017–2021 Polaris RZR 570 (EBS) Standard / Premium – Paddle Tires (WE437669)
Unlock maximum dune performance with the EPI Performance WE437669 Low Elevation Sand Dune Clutch Kit for 2017–2021 Polaris RZR 570 Standard and Premium models equipped with EBS. Specifically engineered for machines running paddle tires at 0–3000 feet elevation, this dune-calibrated CVT tuning kit maintains peak power RPM while delivering stronger low-end torque and crisp throttle response in deep sand.
Paddle tires create substantial rotational drag, especially during steep dune climbs and wide-open acceleration. Without proper clutch recalibration, your RZR 570 can drop out of its optimal power band, leading to sluggish performance and increased belt temperatures. This kit is designed and tested specifically for sand dune applications to ensure consistent power delivery and improved drivability.

Why Upgrade for Paddle Tire Dune Riding?
Paddle tires are essential for serious dune performance but dramatically increase drivetrain load. The EPI WE437669 Sand Dune Clutch Kit recalibrates clutch engagement and backshift characteristics to maintain optimal RPM, improve torque transfer efficiency, and reduce belt temperatures.
The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability — making it an essential performance upgrade for dedicated RZR 570 dune riders.
