EPI Performance Low Elev. Sand Dune Clutch Kit for 2009 Polaris RZR S 800 4×4 – Stock Tires – WE436705

EPI Low Elevation Sand Dune Clutch Kit for 2009 Polaris RZR S 800 4×4 – WE436705

Maximize dune performance with the EPI Performance WE436705 Low Elevation Sand Dune Clutch Kit for the 2009 Polaris RZR S 800 4×4. Specifically engineered for machines running stock tires at 0–3000 feet elevation, this dune-calibrated CVT tuning kit helps maintain peak power RPM while delivering stronger torque and faster throttle response in soft sand conditions.

Sand riding creates constant drivetrain load, especially when climbing steep dune faces or accelerating through deep bowls. Without proper clutch tuning, your RZR S 800 can fall out of its optimal power band, resulting in sluggish performance and excessive belt heat. This kit is designed and tested specifically for sand dune applications to ensure consistent and reliable performance.

Key Features

• Designed for Stock Tires – Optimized clutch calibration for factory tire size.
• Low Elevation Setup (0–3000 ft) – Tuned for sea-level and low-altitude dune riding.
• Maintains Peak Power RPM – Keeps your engine in its optimal power band during climbs.
• Improved Low-End Torque – Stronger launch performance in deep sand.
• Quicker Backshift – Delivers crisp throttle response under aggressive acceleration.
• Reduced Belt Slip – Minimizes clutch heat and extends belt life.
• Sand-Tested Engineering – Designed specifically for demanding dune environments.
