KWI Clutching - Polaris RZR XP 1000 / 4 XP 1000 300 Pro Package

The KWI 300 Pro Package is a complete CVT performance bundle for naturally aspirated Polaris RZR XP models. It combines the X300 Clutch Kit, RZRBlade 300 Billet Inner Primary Sheave, and RZR Overdrive Cover into one fully engineered package designed to address weak points in the factory clutch system.

X300 Clutch Kit includes:

• (3) X300 Adjustable Weights
• White Primary Spring
• Magnet Pack

Delivers smooth, consistent power with adjustability for engagement, RPM control, and backshifting based on your setup, tire size, and riding conditions.

RZRBlade 300 Billet Inner Primary Sheave replaces the factory inner primary sheave with a full billet unit featuring Groovix Cooling Technology. This technology actively draws airflow through the primary clutch under load, reducing belt temperatures and improving clutch efficiency. Includes (6) mounting bolts and washers. Note: Installation must be performed by KWI in their shop to ensure proper fitment and performance.

RZR Overdrive Cover is machined from 7075 billet aluminum, eliminating clutch flex that reduces efficiency. Allows the clutch to shift out further than the factory cover permits, adding 3–5 MPH of top speed and putting more power to the wheels.

Together, these three upgrades reduce belt temperatures, improve durability, and deliver more power than the stock system.
