2018-20 RZR Turbo S 72" Wide S3 Recoil Clutch Kit

The Aftermarket Assassins S3 Recoil Clutch Kit is a primary and secondary clutch upgrade for the 2018 to 2020 Polaris RZR Turbo S. It helps the machine hold RPM, bog less on big climbs and put power to the wheels on larger tires or paddles.

Why it holds up

• AA custom cut helix with a revised shift angle. Factory helixes start steep and go shallow up top, and AA testing found that change too drastic.
• Weights adjust with simple magnets, so the kit can be retuned for new tires or mods without buying extra parts
• Recoil clutch weights carry a custom AA profile and a nitrocarburized coating for wear resistance, fatigue strength and surface lubricity
• Cooler belt temps and longer belt and clutch life, especially with larger tires or paddles
• Close to stock engagement that stays smooth, and works on stock or modified machines

Good to know

• Performance Helix 1031: 2 seat Turbo S on 30 to 33 inch tires or paddles. AA's standard Turbo S helix since the kit was released. Tune for tire size with the weights.
• Performance Helix 1024: 2 or 4 seat on 30 to 33 inch tires or 30 to 32 inch paddles. A softer shift angle from 0 to 25 MPH suits crawling and slow speed work. Also a good choice for lightweight 34 to 35 inch tires.
• High Load Helix 1021: 2 or 4 seat on heavy 34 to 35 inch tires. Slows the shift to keep the secondary from over shifting and slipping the belt.
• Torsion options (1026 performance, 1032 high load): a complete secondary converted to a Torsion spring and helix for better belt grip, less secondary chatter, longer button life and smoother engagement for crawling. The secondary bushing comes peened over so it stays put. Top speed is limited to about 80 to 85 MPH on most models, and AA says to run it with the AA primary clutch limiter.
• The setup guideline lists starting setups for dunes, mud and all around trail riding.
• The only tool needed is AA Compression Tool #1, and the primary parts can be done with the clutch on the machine. Many primary clutches sit tight on the tapered crank, so grease the puller tip and threads if you pull it.
• AA recommends its Snap Ring Delete Kit on 2018 models and the AA Primary Spring Limiter to reduce heat and center the spring.
• For sand or paddles, the AA teal primary spring raises peak RPM 200 to 300 and engages around 2100 to 2300 RPM.
