AA Primary Clutch with Billet Inner Sheave for 2022+ RZR Pro R 4 Cylinder

The Aftermarket Assassins Primary Clutch with Billet Inner Sheave replaces the factory primary on the Polaris RZR Pro R 4 cylinder. OEM sheaves wear from slight slipping and the inner sheave is usually the first to break, so AA made it from billet.

Why it holds up

• Inner sheave machined from 6061 billet aluminum for improved strength and durability
• Cast outer (movable) sheave and spider keep cost down versus a full billet clutch
• Uses factory style springs and weights for an easy swap, or pairs with an AA clutch kit
• Built for higher horsepower turbocharged machines and works on any Pro R

Fits

• 2022 and newer Polaris RZR Pro R 4 cylinder

In the box

• AA primary clutch, sold bare without weights or spring

Good to know

• AA highly recommends running its clutch kit with this clutch.
• Installs like OEM, so instructions are not included. A P90X primary clutch puller is needed to remove the OEM clutch.
• Torque the primary bolt to 140 ft lbs.
• Billet sheaves are not indestructible. Major belt slip or water in the cover still wears a clutch quickly, so seal the cover properly and verify peak RPM and belt slip.
