Spring (Red) - Polaris RZR Pro/Pro R HE Primary Spring

The KWI Red High Engagement Primary Spring is a purpose-built primary spring for Polaris RZR Pro and Pro Rmodels — used as the high engagement spring in the X300, X300T, X302, and X302T Clutch Kits. Available here individually for riders who need a replacement or want to swap engagement characteristics without purchasing a full kit.

The Red Spring raises engagement RPM for a more aggressive clutch feel — delivering harder launches, stronger acceleration off the line, and a more responsive throttle in high-performance applications. Whether you're running a naturally aspirated Pro build or a high-horsepower turbo setup, the Red Spring gives you the higher engagement option that the X300 and X302 series kits are built around.
