Fits All 2024+ RZR XP 1000 Models – Does NOT fit older RZR XP 1000 models.
Take your Polaris RZR XP 1000 to the next level with the 2024+ S4 Clutch Kit with AA Heavy Duty Primary and Secondary Clutches by Aftermarket Assassins. Designed for peak performance, durability, and precision, this clutch kit is built for riders who demand more torque, faster acceleration, and consistent power delivery across all terrains. Whether you’re exploring trails, climbing dunes, or powering through mud, the S4 Recoil Clutch Kit ensures your RZR performs at its best every time you hit the throttle.
This complete kit includes a heavy-duty AA primary clutch featuring an encapsulated tower design — the same proven design found on high-horsepower RZR Turbo models. Constructed with premium-grade tool steel and equipped with AA HD sliders, it offers superior belt grip, smoother engagement, and reduced slippage under high RPMs. The kit also comes with a billet Revolver Clutch Cover with Tower Lock for added strength and improved airflow, ensuring cooler belt temperatures and extended clutch life.
Each clutch kit includes everything you need for installation: AA Primary Clutch with billet Revolver cover, AA magnetic adjustable clutch weights, setup sheet, AA primary spring, Primary Limiter, inner cover bolts, AA replacement secondary clutch, AA Helix, AA secondary spring, and AA Extreme Heavy Duty primary sliders. All components are precision-engineered for optimal performance and easy adjustability, allowing you to fine-tune your setup based on riding style, tire size, and terrain.
The 2024+ RZR XP 1000 factory clutching is designed for high RPM but lacks efficient torque transfer. Aftermarket Assassins solves this with a custom-designed helix and spring combination that transforms how your power reaches the ground. Enjoy stronger midrange pull, up to +6 RWHP in the mid-range, and improved throttle response. Choose from dedicated helix options like the High Load Helix 1067 for heavy tires or mud, or the Performance Helix 1068 for aggressive, high-horsepower setups.
For riders seeking a quieter, smoother experience, the optional “Cruiser” setup reduces cruising RPM for less cabin noise without sacrificing drivability. All setups are easily reversible in minutes, giving you total control over your ride’s feel and performance. Whether you prefer engine braking (EBS) for controlled descents or a freewheeling setup for faster trail riding, the kit accommodates both preferences.
Compatible with tire sizes from 30” to 35” and paddles from 28” to 33”, this clutch kit is ideal for both stock and tuned machines. Expect cooler belt temps, better throttle response, longer belt life, and more consistent clutch performance. Every kit includes detailed setup instructions and tuning recommendations so you can install and ride with confidence.
