KWI Clutching - Polaris RZR Pro R / 4 Pro R / Pro R Boost / 4 Pro R Boost RZRblade 302 Mod

The KWI RZRBlade 302 is a full billet inner primary sheave replacement for the Polaris RZR Pro R. It eliminates one of the most common failure points in the Pro R 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.

Purchasing Options:

• 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.

Aerospace-grade billet construction delivers superior strength and wear resistance beyond the OEM sheave. Groovix cooling draws airflow through the clutch under load, keeping belt temperatures down and maintaining consistent clutch performance in demanding conditions.

Compatible with all Polaris RZR Pro R models.
