Speed UTV Fusion / Speed UTV KWI-Designed Primary Rebuild Kit
Performance clutches are only as good as the components inside them. The Speed UTV Fusion / KWI-Designed Primary Rebuild Kit gives you everything needed to bring your primary clutch back to full spec — restoring smooth engagement, consistent shift RPM, proper belt grip, and the durability your riding demands.
Designed for both the KWI Fusion SPEED Primary Clutch and the newer Speed UTV-produced clutches built on KWI-designed technology, this kit covers the wearable components that take the most abuse in extreme riding conditions. Rollers, shoes, and springs degrade over time — and when they do, you'll feel it in sluggish engagement, inconsistent power delivery, and belt wear that shouldn't be happening.
Whether you're racing desert, pounding rough trails, or running a high-horsepower setup, regular primary clutch maintenance isn't optional — it's what keeps your CVT system operating the way it was designed to. This kit makes that maintenance straightforward, with components built specifically for the Fusion-style SPEED clutch platform so fitment and performance are never a question.
Don't let worn internals rob you of the cooling efficiency, clamping strength, and shift accuracy your clutch was engineered to deliver. Rebuild it right, and keep it there.
