EPI Performance High Elev. Sport Utility Clutch Kit for Polaris RZR S Models – 27-28 Tires Inch

Polaris RZR S High Elevation Clutch Kit for 27–28” Tires (3,000–6,000 ft)

The EPI Performance High Elevation Sport Utility Clutch Kit is engineered for Polaris RZR S models running 27–28 inch tires at elevations between 3,000 and 6,000 feet. Larger tires increase drivetrain load, and higher elevations reduce engine power due to thinner air. This precision-calibrated clutch kit compensates for both factors, restoring acceleration, improving throttle response, and enhancing overall CVT efficiency.

Designed as EPI’s best all-around use kit, this clutch upgrade strengthens low-end torque, improves midrange acceleration, and delivers quicker backshift response. It is ideal for trail riding, occasional mud and sand use, plowing, and hauling applications where consistent power delivery is critical.

Note: This kit will eliminate the factory Engine Braking System (EBS) for performance-oriented clutch tuning.

Key Features

• Designed for 27–28” Tires: Recalibrates clutch engagement to compensate for oversized tire setups.
