EPI Performance High Elev. Sport Utility Clutch Kit for 2009 Polaris RZR S 800 with Full Exhaust System – Stock Tires

EPI High Elevation Sport Utility Clutch Kit for 2009 Polaris RZR S 800 – Stock Tires (Full Exhaust Equipped)

Maximize mountain performance with the EPI Performance High Elevation Sport Utility Clutch Kit for the 2009 Polaris RZR S 800 equipped with a full exhaust system. Specifically engineered for machines running stock tires at elevations between 3,000–6,000 feet, this precision CVT tuning kit restores lost horsepower at altitude while optimizing throttle response and torque delivery.

Higher elevations reduce engine output due to thinner air, and aftermarket exhaust upgrades alter airflow characteristics. Proper clutch calibration is critical to maintain peak RPM and drivability. This EPI clutch kit recalibrates engagement and backshift characteristics to keep your RZR operating in its optimal power band under load.

Key Features

• Designed for Stock Tires – Optimized clutch tuning for factory tire size.
• Calibrated for Full Exhaust Systems – Engineered to complement performance exhaust upgrades.

Why Upgrade for High Elevation with Performance Exhaust?

At 3,000 feet and above, engines lose horsepower — and performance exhaust systems can further alter power delivery characteristics. Without proper clutch recalibration, acceleration and throttle response can suffer. The EPI High Elevation Sport Utility Clutch Kit restores performance by maintaining optimal RPM and improving torque transfer efficiency.

The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved durability — making it a smart upgrade for RZR S 800 owners running full exhaust systems in mountain environments.
