EPI Low Elevation Sand Dune Clutch Kit for 2016–2025 Polaris Sportsman 450 HO – Stock Tires (WE437568)
Maximize dune performance with the EPI Performance WE437568 Low Elevation Sand Dune Clutch Kit for 2016–2025 Polaris Sportsman 450 HO models. Specifically engineered for machines running stock tires at 0–3000 feet elevation, this dune-calibrated CVT tuning kit maintains peak power RPM while delivering stronger low-end torque and improved throttle response in soft sand conditions.
Sand riding places sustained load on your drivetrain, especially during steep dune climbs and wide-open acceleration. Without proper clutch recalibration, your Sportsman 450 HO can drop out of its optimal power band and generate excessive belt heat. This kit is designed and tested specifically for sand dune applications to ensure consistent RPM control and reliable power delivery.
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 operating in its optimal power band during climbs.
- Improved Low-End Torque – Stronger launch performance in deep sand.
- Quicker Backshift – Crisp throttle response under aggressive acceleration.

Why Upgrade for Dune Riding?
Deep sand increases drivetrain resistance and can cause RPM drop and excessive clutch temperatures. The EPI WE437568 Sand Dune Clutch Kit recalibrates clutch engagement and backshift characteristics to maintain proper operating RPM, improve torque transfer efficiency, and reduce belt slip.
The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability — making it an essential performance upgrade for Sportsman 450 HO owners who ride in the dunes.
