KWI Clutching - Polaris RZR XP RZRblade 300 Mod

The KWI RZRBlade 300 is a full billet inner primary sheave replacement for Polaris RZR XP models with P90X primaries. It eliminates one of the most common failure points in the RZR XP clutch system by replacing the factory inner sheave with a single piece of aerospace-grade billet aluminum engineered to withstand high-performance riding loads.

Features include KWI Groovix Cooling Technology on the backside to actively manage belt temperatures and extend belt life under hard riding conditions. Aerospace-grade billet construction delivers superior strength and wear resistance far beyond the OEM sheave, while Groovix cooling draws airflow through the clutch under load to keep belt temperatures down and maintain consistent clutch performance.

Two purchasing options are available:

• Core Exchange — send in your inner sheave before shipment. KWI installs it, reinforces your clutch, and returns it ready to bolt on.
• Outright Purchase — no core required; your order ships immediately.

Compatible with all Polaris RZR XP models with P90X primaries.
