Compatibility & Application
This clutch kit is designed exclusively for the 2015 Polaris Ranger 900 equipped with EBS and running stock tire size. It is calibrated for dune environments where maintaining peak RPM and minimizing belt slip are critical for consistent power delivery.
Why Choose the EPI Sand Dune Clutch Kit?
Factory clutch calibration is designed for general-purpose riding. In sand, however, improper clutching can cause power loss, excessive belt wear, and overheating. This performance clutch kit recalibrates your CVT system to better match dune terrain, allowing your Ranger to stay in its optimal power band under heavy load.
Whether you’re climbing steep faces or cruising through open sand bowls, this kit provides smoother engagement, faster backshift, and improved durability—making it a reliable upgrade for serious dune riders seeking stronger performance and better throttle control.
