KWI UltraShift Fusion XR Pro R Secondary Clutch

The KWI UltraShift Fusion XR Secondary Clutch for Polaris RZR Pro R is the next evolution in high-performance CVT clutching. Designed for racers and serious performance enthusiasts, the Fusion XR introduces true floating secondary clutch technology to the Pro R platform—delivering unmatched efficiency, adjustability, and durability.

Built entirely from billet aluminum, the Fusion XR uses KWI’s proven floating clutch hub system, allowing the clutch to self-align with the primary under load. This eliminates side-load on the belt, reduces friction, lowers belt temperatures, and dramatically improves belt life and drivetrain efficiency.

Paired with the DR3 Groovix Helix, the same system used in KWI’s championship-winning Can-Am X3 setups, the Fusion XR delivers strong belt grip, quick backshifting, and improved cooling. The result is smoother shifting, more consistent RPM control, and increased wheel horsepower compared to factory clutch systems.

Key Features

• Patent Pending floating secondary clutch system
• Designed specifically for Polaris RZR Pro R
• Fully billet machined construction
• Uses DR3 Groovix Helix (Can-Am style)
• Self-aligning clutch design for perfect belt alignment
• Reduces belt heat and friction
• Improves wheel horsepower and drivetrain efficiency
• Compatible with multiple belt lengths for ratio tuning
• Made in the USA

Performance Benefits

Floating Secondary Technology

The Fusion XR utilizes KWI’s floating hub design, allowing the secondary clutch to move laterally on the gearbox shaft. This enables the clutch to automatically align with the primary clutch during operation.

Benefits include:

• Reduced belt side-load
• Improved belt alignment
• Lower belt temperatures
• Extended belt life

Increased Wheel Horsepower

By reducing friction and optimizing belt contact across the sheaves, the Fusion XR improves drivetrain efficiency and frees up additional power to the wheels.

DR3 Groovix Helix Performance

The included DR3 Groovix Helix provides:

• Strong belt grip
• Quick backshifting
• Enhanced clutch cooling
• Improved performance under high load

Adjustable Gear Ratio with Belt Length

For the first time on the Polaris Pro R platform, riders can adjust gearing simply by changing belt length.

This allows you to quickly tune your machine for:

• Higher top speed
• 15% lower gearing for rock crawling
• Optimized setups for dunes, desert, trails, or short-course racing

Why It Matters

The stock Polaris Pro R secondary clutch is fixed in place and can become misaligned under heavy load. This causes:

• Belt heat buildup
• Uneven belt wear
• Inconsistent RPM control

The Fusion XR floating design eliminates these problems, ensuring perfect belt-to-sheave contact and delivering the most efficient power transfer possible.

FAQ

What makes the Fusion XR different from the stock Pro R secondary?

The Fusion XR uses a floating hub system, allowing the clutch to self-align with the primary for better belt contact and improved performance.

Does this help reduce belt failures?

Yes. Improved belt alignment and reduced friction help lower belt temperatures and extend belt life.

Can I change gearing with this clutch?

Yes. The Fusion XR allows riders to change gear ratio by running different belt lengths, making it easy to tune your setup.

Is this clutch good for racing?

Absolutely. It is designed for high-performance and race applications, including dunes, desert racing, rock crawling, and short-course setups.
