EPI High Elevation Sport Utility Clutch Kit for 2015 Polaris RZR Trail 50” 900 EBS

Take back lost power at altitude with the EPI Performance High Elevation Sport Utility Clutch Kit for the 2015 Polaris RZR Trail 50” 900 EBS. Specifically calibrated for 27–28 inch tires and elevations between 3,000–6,000 feet, this all-around CVT tuning kit restores throttle response, improves torque delivery, and optimizes clutch performance in thinner mountain air.

When you combine higher elevation riding with oversized tires, your machine can feel sluggish and unresponsive. This EPI clutch kit compensates for reduced engine power and added tire mass, ensuring your RZR maintains proper operating RPM for stronger acceleration and smoother engagement. The kit also eliminates the factory Engine Braking System (EBS), providing more predictable clutch behavior.

Why Upgrade Your Clutching at High Elevation?

At elevations above 3,000 feet, engine performance naturally drops due to lower air density. Adding 27–28” tires increases rotational mass, further reducing responsiveness. This EPI High Elevation Sport Utility Clutch Kit recalibrates your CVT system to maintain peak operating RPM, improve torque transfer efficiency, and reduce clutch heat buildup.

Whether you’re navigating mountain trails or putting your RZR to work, this performance-focused upgrade delivers smoother engagement, stronger acceleration, and improved durability — making it a smart, long-term investment for high-altitude riders.
