KWI RZRBlade 300 Billet Inner Sheave Mod for Polaris RZR XP (P90X)

The KWI RZRBlade 300 Mod for Polaris RZR XP is a heavy-duty billet inner sheave upgrade designed to replace the weak OEM inner sheave found in P90X primary clutch systems. Built from aerospace-grade billet aluminum, the RZRBlade 300 dramatically improves clutch durability while helping reduce belt temperatures and clutch wear.

Factory inner sheaves are known to fail under high load or aggressive riding conditions. The RZRBlade 300 eliminates this weak point, providing a stronger, wear-resistant component engineered to withstand high-horsepower setups and demanding off-road use. The integrated KWI Groovix Cooling Technology on the backside of the sheave helps improve airflow and reduce belt heat, keeping your CVT system running cooler and more efficiently.

Whether you're pushing dunes, running desert terrain, or aggressively trail riding, the RZRBlade 300 upgrade provides increased reliability, improved cooling, and longer belt life for Polaris RZR XP machines.
