2020 ONLY RZR Pro XP S3 Clutch Kit with AA Heavy Duty Primary

The Aftermarket Assassins S3 Clutch Kit with Heavy Duty Primary is a complete clutch upgrade for the 2020 Polaris RZR Pro XP. It fixes the poor belt grip of the factory P90X setup and works from stock machines up to 330 crank HP big turbo builds.

Why it holds up

• Encapsulated tower primary, the same design found on 2016 to 2020 RZR Turbo models, built with a higher grade tool steel post
• Billet Revolver Clutch Cover with Tower Lock for added strength and airflow
• AA Extreme Heavy Duty primary sliders come installed
• Stiffer secondary spring for belt grip and an AA custom cut helix for harder acceleration
• Better power transfer and lower belt temps than the OEM P90X clutch

Fits

• 2020 Polaris RZR Pro XP, 2 and 4 seat
• Does not fit 2021 and newer models, as the helix design changed

In the box

• AA primary clutch with billet Revolver cover
• Primary bolt
• AA magnetic adjustable clutch weights and weight setup sheet
• AA primary spring
• Custom primary spring limiter
• AA secondary spring
• AA custom cut helix
• AA Extreme Heavy Duty primary sliders, installed

Good to know

• Performance Helix 1043: aggressive, for acceleration and higher horsepower. 2 seat: 30 to 33 inch dirt tires, 30 to 32 inch paddles. 4 seat: 30 to 32 inch dirt tires, 28 to 30 inch paddles.
• High Load Helix 1042: slightly less aggressive, for heavier vehicles, heavier tires, sand load or crawling. 2 seat: 30 to 35 inch dirt tires, 30 to 32 inch paddles. 4 seat: 30 to 33 inch dirt tires, 28 to 32 inch paddles.
• Ships unassembled. Set the weights from the setup chart, then install the weights and spring.
• Engagement is slightly higher, around 1800 to 2000 RPM, and still smooth
• This clutch is louder at idle and tight under the cover; it may lightly contact the cover at idle in rare cases
• The primary bolt head is turned down to clear the cover. Use an 18mm 6 point socket and take care when tightening.
