2024+ RZR XP 1000 S1 Clutch Kit

The Aftermarket Assassins S1 Clutch Kit corrects the factory clutching on the 2024 and newer Polaris RZR XP 1000, which winds out RPM off the line and does not transfer torque until peak RPM. AA weights, spring and limiter washer put the power to the rear tires and add belt grip for larger tires.

Why it holds up

• Magnetic adjustable weights, easily adjusted if needed
• Gains shown on the dyno and felt on the trail
• Cooler belt temps and longer belt and clutch life, especially with larger tires or paddles
• Works with stock or modified machines
• Very slightly higher engagement that stays smooth

Fits

• 2024 and newer Polaris RZR XP 1000, 2 and 4 seat
• 2026 and newer Polaris RZR XP 1000 S (72 inch), 2 and 4 seat
• Works well with 30 to 33 inch tires and 28 to 32 inch paddles

In the box

• AA magnetic adjustable clutch weights
• AA primary spring
• AA primary limiter washer
• Setup guideline for dunes, mud and trail, with brief install instructions

Good to know

• Cruiser setup on the included sheet loads the weights heavier for lower cruising RPM and less noise, dropping peak RPM to roughly 7500 to 7800 from the factory 8300 to 8600. It gives up a little horsepower; switch back to the standard setup any time in 15 to 30 minutes.
• For larger tires or more performance, AA recommends the S3 kit with helix and secondary spring
• The only special tool needed is clutch compression tool #1; a clutch puller makes installing the weights and spring easier
• AA suggests the alignment shim kit, since OEM clutches are often not shimmed correctly
• Optional AA Stryker belt and Revolver billet clutch cover with Tower Lock
