The UltraShift Series by KWI
Power. Durability. Reliability. KWI’s UltraShift billet primary clutches are engineered to take the abuse that stock clutches can’t. Whether you ride a Can-Am X3, RZR XP, Turbo R, or Pro R—we’ve got an UltraShift model tailored for your platform and built to perform under the harshest conditions. Say goodbye to belt failures and wasted horsepower. Say hello to the future of clutching.
Billet Built. Race Proven.
Every UltraShift clutch is machined in-house from aerospace-grade billet for unmatched strength and precision. No cast parts. No shortcuts. Just battle-tested hardware that performs when it counts.
Cooler Temps. Better Grip.
Our exclusive Groovix Cooling Technology reduces belt temps and improves airflow where it matters most. That means more consistent performance, better belt life, and smoother engagement in every terrain.
Custom Tuning Power
Whether you’re stock, tuned, or pushing 700+ HP, the UltraShift gives you full control. Compatible with 3, 4, or 6 cam arms, every clutch is tailored to your setup and riding goals—no guessing, no compromises.

The UltraShift Series is KWI’s answer to the weak links in factory primary clutch designs. Stock clutches aren’t built to handle the heat, stress, or power that modern UTVs are putting down—especially once you start tuning. That’s where UltraShift steps in.
Each UltraShift clutch is a fully billet primary system precision-machined in-house from aerospace-grade materials. It’s built to eliminate belt failures, improve belt grip, and put more of your engine’s power to the wheels. From the dunes to the rocks to the track, this is the clutch you want on your machine when performance matters.
