About this product

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.

Why it matters

Clutch wear is gradual — most riders don't notice it until performance has already dropped significantly. Rebuilding on a regular maintenance schedule prevents belt slip, protects your drivetrain, and extends the life of the clutch itself.
