Why Upgrade for Sand Dune Riding?

Sand creates high drag and continuous load on your CVT system. Without proper clutch calibration, your RZR may struggle to maintain RPM, overheat belts, and lose valuable torque during climbs. The EPI WE437222 Sand Dune Clutch Kit recalibrates your clutching to improve torque transfer efficiency and minimize belt slip under demanding dune conditions.

Whether you’re carving bowls or climbing steep faces, this purpose-built dune clutch kit delivers consistent RPM control, faster backshift response, and improved overall reliability — making it an essential upgrade for serious sand riders.
