Why Choose the EPI High Elevation Clutch Kit?

Higher elevation reduces engine horsepower, while oversized tires add extra drivetrain load. Without proper clutch calibration, these factors can lead to sluggish acceleration and increased clutch heat. This EPI clutch kit recalibrates your ATV’s CVT system to maintain proper operating RPM and restore responsive performance.

If you ride in mountain terrain or higher elevation areas with larger tires installed, this heavy-duty clutch upgrade ensures improved torque delivery, better throttle response, and long-lasting drivetrain durability.
