KWI Clutching - Kawasaki Teryx H2 / 4 H2 / 5 H2 Fusion System Bundle

The KWI Fusion H2 System Bundle is the most complete CVT upgrade available for the Kawasaki H2 platform. This fully integrated system combines the Fusion H2 Primary Clutch, Fusion H2 Floating Secondary Clutch, DR3 Groovix Helix, Kwik Change Belt Tool, Quick Release Helix Cover, and your choice of belt — engineered as one optimized package.

The factory Kawasaki H2 clutch system was not designed for serious riding demands. Belt heat builds quickly and stays high. Backshifting is sluggish and inconsistent. The fixed secondary hub creates side-load under torque, accelerating belt wear. RPM control is unpredictable across elevation and terrain changes. The Fusion H2 System solves these problems with precision engineering and real tuning flexibility.

The Fusion H2 Primary features fully billet, CNC-machined construction using aerospace-grade materials. It delivers precise, repeatable engagement with adjustable weights and a precision-tuned spring for real tuning control across the full RPM range. Dial in performance for sea-level desert racing or high-elevation trail riding.

The Fusion H2 Floating Secondary features KWI's floating hub design that self-aligns under load, eliminating misalignment from fixed secondary systems. This delivers cleaner belt contact, dramatically reduced side-load and friction, lower operating temperatures, and extended belt life. Paired with the DR3 Groovix Helix, you gain aggressive backshifting, superior belt grip, and active airflow cooling that draws heat out of the clutch under load.

Adjust final drive ratio through belt selection without gearbox changes:

• Gates KRX 47R4738 Belt — approximately 5% gear reduction, ideal for top-end speed, dunes, and desert riding
• OEM Pro R Belt — approximately 15% gear reduction, providing crawling torque and control for rocks, mud, and technical terrain

The Fusion H2 System has been tested and proven in demanding off-road environments including King of Hammers, high-altitude desert racing, and rock crawling. This battle-tested platform has thousands of miles of real-world validation.
