Why Upgrade for Dune Riding?

Even with stock tires, sand creates high drag and constant resistance that can pull your engine out of its optimal RPM range. Without proper clutch calibration, you may experience sluggish response, excess belt heat, and reduced climbing performance.

The EPI WE437040 Sand Dune Clutch Kit recalibrates your CVT system to improve power delivery, optimize backshift, and maintain peak RPM during aggressive dune riding. Whether you’re carving bowls or powering up steep faces, this kit delivers stronger acceleration and more consistent performance in harsh sand conditions.

If you ride dunes at low elevation, upgrading your clutching is one of the most effective ways to unlock reliable, high-performance results from your RZR 900 XP or XP4.
