Upgrade your Polaris RZR XP 1000 with the S3 Clutch Kit by Aftermarket Assassins—one of the most effective performance modifications you can make to your UTV. Designed for riders who demand instant throttle response, consistent power delivery, and improved clutch efficiency, this kit transforms how your machine performs across trails, dunes, and mud. Whether you’re racing, crawling, or cruising, the S3 clutch kit ensures your RZR pulls harder, accelerates faster, and maintains superior belt grip under heavy loads.
The 2024 RZR XP 1000 comes from the factory with a clutch calibration that limits torque transfer until reaching peak RPM. The S3 Clutch Kit solves this issue with precision-engineered components, including a custom-cut helix, magnetic adjustable clutch weights, and matched primary and secondary springs. This optimized setup delivers immediate torque response, increased power to the wheels, and cooler belt temperatures for longer belt and clutch life. Testing shows gains of up to 6 rear-wheel horsepower in the mid-range and 1 horsepower at peak speeds, ensuring noticeable improvements in real-world performance.
Available in multiple configurations, the kit includes both Performance and High Load Helix options. The Performance Helix (1068) delivers aggressive acceleration for tuned, fast-paced two-seat models, while the High Load Helix (1067) offers smoother, more controlled power for heavier vehicles, four-seat models, or those running larger 30–35 inch tires or 28–33 inch paddles. For riders seeking a quieter experience, the Cruiser setup lowers RPM and reduces cabin noise without sacrificing smooth engagement or drivability.
Built to work seamlessly with both stock and modified machines, this clutch kit is ideal for drivers running larger tires, paddles, or aftermarket tunes. It provides more efficient power transfer, cooler operating temps, and consistent clutch performance even under demanding conditions. The included setup guide outlines optimal configurations for dunes, trails, and mud, making installation and tuning straightforward. With easily adjustable weights and optional Butter Shift washers available for even smoother shifting, the S3 Clutch Kit by Aftermarket Assassins is a must-have upgrade for maximizing the performance, reliability, and versatility of your Polaris RZR XP 1000.
