EPI Low Elevation Sand Dune Clutch Kit for 2015 Polaris RZR XP / XP 4 – WE437250

Maximize dune performance with the EPI Performance WE437250 Low Elevation Sand Dune Clutch Kit for the 2015 Polaris RZR XP and RZR XP 4. Specifically calibrated for 0–3000 feet elevation and stock tires, this dune-focused CVT clutch kit keeps your engine operating in its peak power RPM range while delivering stronger torque and sharper throttle response in soft sand conditions.

Sand riding creates constant drivetrain load, especially during hill climbs and aggressive acceleration. Without proper clutch calibration, your RZR can lose RPM efficiency, experience belt slip, and generate excessive heat. This kit is designed and tested specifically for sand dune applications to ensure consistent power delivery and improved durability.

Key Features

• Low Elevation Calibration (0–3000 ft) – Precision-tuned for optimal dune performance at lower altitudes.
• Designed for Stock Tires – Direct-fit clutch setup for factory tire size.
