REVOLUTIONIZE YOUR RIDE WITH THE KWI ULTRASHIFT
KWI set out on a goal to fully redefine the CVT drive system and eliminate belt failures for good. We called this project UltraShift. After years of relentless engineering and exhaustive field tests, we are proud to bring you the first major step toward that complete vision - the UltraShift Billet Primary Clutch. Your passport to unmatched off-road power and belt grip. This state-of-the-art billet clutch is a new level of durability, efficiency, and versatility, setting a new standard in off-road performance. Developed through meticulous engineering, rigorous testing, and zero compromises, UltraShift isn't just another clutch—it's a game-changer.
If you're embarking on a thrilling journey through rugged terrain that demands a clutch system that can keep up, the UltraShift is that clutch. Bid farewell to belt slip, lost horsepower, poor cooling, and short-lived belts; UltraShift is what you've been waiting for.
Specifically engineered for you, the UltraShift optimizes vehicle-specific airflow and cooling efficiency. Built with high-strength aerospace materials and featuring our unique Groovix cooling technology. If you're looking to push the limits in rugged terrains, the KWI UltraShift has got you covered.
Unbeatable Durability Meets Lightweight Innovation
Made with ultra-high-strength aerospace materials, this clutch is built to withstand the most extreme conditions. The use of quality materials allows us to build a much stronger clutch that is 1-2 pounds lighter than OEM clutches and can take all the horsepower you can throw at it.
Revolutionary Cooling Technology
The UltraShift is tailored to boost your vehicle's clutch cooling with a model-specific design. It features our unique Groovix cooling technology and a longer belt for lower temperatures and prolonged belt life. Unlike generic one-size-fits-all solutions, UltraShift is custom-engineered for optimal airflow and cooling, ensuring top performance for your specific vehicle.
ULTRASHIFT WITH 3 CAM ARMS
ULTRASHIFT WITH 4 CAM ARMS
ULTRASHIFT WITH 6 CAM ARMS
The ability to use 3, 4, or 6 cam arms so you can tune to your power level from stock to 700+HP, the UltraShift can take it. This empowers you to customize cam arm settings based on your unique requirements—terrain, tire size, horsepower, and altitude. Designed using the KWI AOP-1 clutch weights, however, it will accept most PDrive style cam arms on the market if you want to experiment.
