EPI Performance High Elev. Sport Utility Clutch Kit for 2009 Polaris RZR S 800 with Full Exhaust System – 27-28” Tires

EPI High Elevation Sport Utility Clutch Kit for 2009 Polaris RZR S 800 – 27–28” 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 27–28 inch tires at elevations between 3,000–6,000 feet, this precision CVT tuning kit restores lost horsepower while compensating for the added load of oversized tires.

Higher elevations reduce engine output due to thinner air, and larger tires increase rotating mass and drivetrain resistance. Combined with a performance exhaust system, proper clutch calibration becomes critical to maintain peak power RPM and drivability. This EPI clutch kit recalibrates engagement and backshift characteristics to keep your RZR operating in its optimal power band.

Key Features

• Designed for 27–28” Tires – Optimized to offset performance loss from oversized tires.
• Calibrated for Full Exhaust Systems – Engineered to complement performance exhaust upgrades.
• High Elevation Setup (3,000–6,000 ft) – Tuned for mountain riding conditions.
• Best All-Around Use Kit – Ideal balance for recreation and utility use.
• Improved Low-End Acceleration – Stronger takeoff power at altitude.
• Enhanced Midrange Performance – Better throttle response across the power band.
• Quicker Backshift – Crisp engagement during terrain changes.
• Reduced Belt Slip – Minimizes clutch heat and extends belt life.

Why Upgrade for 27–28” Tires at Elevation?

Running larger tires at 3,000–6,000 feet without recalibrating your clutch system can significantly reduce acceleration and throttle response. The EPI High Elevation Sport Utility Clutch Kit restores performance by compensating for altitude-related power loss and increased tire load, ensuring optimal RPM control.

The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability — making it a smart upgrade for modified RZR S 800 owners riding in mountainous terrain.
