EPI Performance High Elev. Sport Utility Clutch Kit for 2012-14 Polaris RZR 900 – 27-28 Tires – WE437038 Inch

EPI High Elevation Sport Utility Clutch Kit for 2012–2014 Polaris RZR 900 – WE437038

Upgrade your 2012–2014 Polaris RZR 900 with the EPI Performance WE437038 High Elevation Sport Utility Clutch Kit. Specifically engineered for machines running 27–28 inch tires at elevations between 3,000–6,000 feet, this precision CVT tuning kit restores lost power at altitude while improving acceleration and throttle response.

Higher elevations reduce engine horsepower due to thinner air, and larger tires increase rotating mass and drivetrain load. Without proper clutch recalibration, these factors can result in sluggish performance and excessive belt heat. This EPI clutch kit maintains optimal RPM under load, delivering stronger low-end torque and smoother midrange pull across demanding terrain.

Key Features

• Designed for 27–28” Tires – Optimized to offset performance loss from larger tire upgrades.
• High Elevation Calibration (3,000–6,000 ft) – Tuned for mountain riding conditions.
• Best All-Around Use Kit – Balanced setup for recreation and utility applications.
• Improved Low-End Acceleration – Stronger takeoff power at altitude.
• Enhanced Midrange Performance – Better throttle response across the power band.
• Quicker Backshift – Crisp throttle engagement during terrain changes.
• Reduced Belt Slip – Minimizes clutch heat and extends belt life.
• Improved Torque Transfer Efficiency – Maintains proper operating RPM under load.

Why Upgrade for 27–28” Tires at Elevation?

Running oversized tires at 3,000–6,000 feet without recalibrating your clutch system can significantly reduce acceleration and drivability. The EPI WE437038 Sport Utility Clutch Kit restores lost performance by compensating for altitude-related power loss and increased tire load, keeping your RZR 900 in its optimal power band.

The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability — making it a smart upgrade for mountain riders and working machines alike.
