RPM RMK Boost & 9r P22 Billet Lightweight COOLER Primary Clutch Cover Brace

Eliminate tower flex, protect your primary clutch assembly, and lower drive belt temperatures on your Polaris with RPM’s Machined 6061 Billet Aluminum P22 Clutch Brace! While the factory Polaris P22 clutch offers great performance, its weak OEM cast cover flexes both outward and side-to-side under heavy spring pressures and extreme high-RPM loads—leading to premature belt wear, clutch tower fatigue, and erratic shifting.

Precision CNC-machined from solid 6061 billet aluminum, this heavy-duty brace replaces the soft stock cast piece to deliver maximum structural rigidity without adding unnecessary rotational weight. To further boost performance, RPM integrated raised fan blades directly into the brace body—turning your clutch cover into a high-output reinforced cooling fan! This drastically increases CFM airflow through the clutch sheaves, drawing heat away from the primary and secondary clutch faces to extend drive belt life and maintain consistent shift performance during prolonged, hard mountain pulls.

The unit arrives ready for a fast, simple bolt-on installation, complete with a pre-installed premium oil-less bushing and a durable anodized black finish.

Key Features:

• Reinforces P22 Primary Clutch: Eliminates outward and lateral side-to-side clutch tower flex to safeguard internal clutch components under peak loads.

• Integrated Airflow Fan Blades: Custom raised fan architecture acts as a reinforced cooling fan, dramatically increasing CFM air movement across the clutches to lower belt temperatures.

• CNC-Machined 6061 Billet Aluminum: Substantially stronger than the fragile OEM cast cover while maintaining an ultra-lightweight footprint.

• Pre-Installed Oil-Less Bushing: Comes pre-fitted with a high-durability oil-less bronze/composite bushing for smooth cover operation right out of the box.

• Anodized Black Finish: Provides superior surface hardness, heat dissipation, and long-lasting protection against corrosion and snow melt.

• Direct Bolt-On Upgrade: Installs seamlessly onto the factory P22 primary clutch using stock or upgraded RPM titanium hardware with zero modifications required.
