EPI WE437648 Performance Clutch Kit for ATV / UTV

The EPI WE437648 is a performance CVT clutch kit engineered by EPI Performance — the #1 aftermarket clutch brand trusted by dealers, racers, and off-road enthusiasts worldwide. EPI Performance has been developing extreme-duty driveline components for ATVs, UTVs, and snowmobiles since 1991, and this kit reflects decades of real-world clutch tuning expertise.

This clutch kit is designed to optimize the CVT (Continuously Variable Transmission) system's shift characteristics, restoring and improving performance for your specific machine and riding application. By recalibrating engagement RPM, shift curves, and backshift response, the WE437648 delivers noticeable gains in drivability and drivetrain efficiency.

Key Features:

• Improved low- and mid-range acceleration for stronger pull out of corners and off the line
• Quicker backshift for crisp, responsive throttle feel
• Reduced belt slippage and clutch heat for longer belt and clutch life
• Better use of available engine torque across the RPM range
• Field-tested design validated for real-world riding conditions
• Engineered for stock engine and exhaust configurations

EPI clutch kits include application-specific springs, weights, and/or rollers that work together as a calibrated system. Kit components vary by model and application. Note: Installation requires a Primary Clutch Puller and Clutch Compression Tool (sold separately). Backed by EPI's 1-year warranty against defects in materials and manufacturing.
