Precision-Built, Trail-Tested, and Made to GO FAST
RZR Clutches That Go the Distance
KWI Clutching builds performance clutches for Polaris RZR owners who demand more from their machines. Whether you’re hammering dunes, climbing through rocky trails, or pushing limits on race day, our upgraded RZR clutches are engineered to transfer power efficiently, reduce belt wear, and improve throttle response in all conditions. These aren’t stock replacements, they’re upgrades built for the bold. Designed and tested in the USA, each clutch is precision-machined to handle heat, load, and terrain like no OEM part can.
Why Upgrade Your Polaris RZR Clutch?
Stock clutches do the job, but just barely. Factory setups are designed for broad use cases and mild abuse. They don’t consider added power, bigger tires, gear changes, or extreme riding. That’s where KWI Clutching comes in.
Our Polaris RZR clutch systems are designed for real riders who run harder and expect more. When you swap to a KWI clutch, you’re getting:
- Stronger belt grip with less slip
- More consistent RPMs across throttle positions
- Smoother engagement and better backshift response
- Drastically improved durability over stock
The KWI Advantage – What Makes Our RZR Clutches Different?
At KWI, every clutch is built from the ground up with racing-grade tolerances and performance tuning in mind. We use billet materials, reinforced sheave machining, and proven geometry that maximizes grip while minimizing wear.
Each clutch is:
- Precision-Machined In-House: We control every step of production for consistency and reliability.
- Backed by Real-World Data: Our clutches are tested by top racers and hardcore weekend warriors in the roughest terrain.
- Built to Handle More: Whether you’re tuned, running 35s, or just want peace of mind—our clutches are built for the punishment.
Unlocking Peak Performance with Proper Calibration
A clutch is only as good as its setup. That’s why every KWI RZR clutch system is designed to work hand-in-hand with precise calibration options.
Proper calibration ensures:
- Optimal RPMs in your motor’s power band
- Minimal belt slip
- Faster throttle response
- Reduced wear on your entire CVT system
With adjustable weights and spring configurations available across the X300 clutch kit and the X302 clutch kit, riders can tune their clutch to match terrain, tire size, elevation, and more.
