RZRblade 300 Mod (XP)
The KWI RZRBlade 300 is a full billet inner primary sheave replacement for Polaris RZR XP models with P90X primaries — engineered to eliminate one of the most common and costly failure points in the RZR XP clutch system. The factory inner sheave is known to fail under the loads generated by high-performance XP riding. The RZRBlade 300 replaces it with a single piece of aerospace-grade billet aluminum built to withstand whatever you throw at it, backed by KWI Groovix Cooling Technology on the backside to actively manage belt temperatures and extend belt life under hard riding conditions.
The RZRBlade 300 is available in two purchasing options. Core Exchange — send in your inner sheave before we ship your RZRBlade, and we'll install it and return your clutch fully reinforced and ready to bolt on. Outright Purchase — no core required, your order ships immediately.
Aerospace-grade billet construction delivers superior strength and wear resistance far beyond the OEM sheave — combined with Groovix cooling that draws airflow through the clutch under load, keeping belt temperatures down and clutch performance consistent in the most demanding conditions.
Compatible with all Polaris RZR XP models with P90X primaries.
