2022+ RZR Pro R 4 Cylinder S3 Clutch Kit

The Aftermarket Assassins S3 Clutch Kit for the Polaris RZR Pro R 4 cylinder adds the belt grip the factory P90X clutching lacks, so the big motor ramps RPM faster and puts its torque to the tires.

Why it holds up

• Custom AA helix and stiffer secondary spring with the right primary weight and spring for proper RPM and belt grip
• Nearly 7 RWHP of ramp up power at roughly 40 MPH over the OEM helix with the S2 kit
• Smaller roller pocket without the EBS notch for much less roller noise and longer roller life, while keeping strong engine braking
• Recoil weights with a custom AA profile and nitrocarburized coating, adjustable with simple magnets
• Ran a 350 mile wide open Iceman race on one belt with life left

Fits

• 2022 to 2026 Polaris RZR Pro R 4 cylinder, 2 and 4 seat
• Does not fit 2027 Pro R Boost models
