EPI Performance Low Elev. Sport Utility Clutch Kit for 2009 Polaris RZR S 800 – 27-28 Tires Inch

EPI Low Elevation Sport Utility Clutch Kit for 2009 Polaris RZR S 800 – 27–28” Tires

Restore performance and throttle response on your 2009 Polaris RZR S 800 with the EPI Performance Low Elevation Sport Utility Clutch Kit, engineered specifically for machines running 27–28 inch tires at 0–3000 feet elevation. This precision CVT tuning kit is calibrated for RZR models equipped with a full exhaust system and EFI controller, ensuring proper clutch performance for modified setups.

Adding 27–28” tires increases rotating mass and drivetrain load, while performance exhaust upgrades alter engine characteristics. Without proper clutch recalibration, acceleration can feel sluggish and belt temperatures can rise. This EPI clutch kit maintains optimal RPM under load, delivering stronger low-end torque and improved midrange acceleration.

Key Features

• Designed for 27–28” Tires – Optimized to offset performance loss from oversized tires.
• Calibrated for Full Exhaust & EFI Controller – Engineered for modified RZR S 800 setups.
• Low Elevation Setup (0–3000 ft) – Tuned for strong low-altitude performance.

Why Upgrade for 27–28” Tires with Performance Mods?

Running larger tires and a full exhaust system without recalibrating your clutch system can reduce responsiveness and increase drivetrain stress. The EPI Low Elevation Sport Utility Clutch Kit restores performance by improving torque transfer efficiency and keeping your engine in its optimal RPM range.

The result is stronger acceleration, smoother engagement, cooler clutch operation, and improved long-term durability — making it an essential upgrade for modified RZR S 800 owners.
