Fits ONLY 2022–2025 Polaris RZR Pro-R 4 Cylinder Models
Enhance your Polaris RZR Pro-R’s power delivery and performance with the Aftermarket Assassins Custom Cut Helix. Engineered with precision for the 4-cylinder Pro-R platform, this helix is designed to maximize rear wheel horsepower transfer through a specialized custom angle that goes beyond the mild factory setup. The result is quicker acceleration, improved throttle response, and superior efficiency without compromising belt grip or drivability.
This performance helix not only boosts power but also refines your ride experience. The custom roller pocket design dramatically reduces roller and ratcheting noise during transitions between load and unload, offering smoother operation and a quieter driveline. With no EBS notch, it still maintains strong engine braking—especially in low gear—while prolonging secondary clutch roller life. It’s the perfect combination of performance, reliability, and refinement.
The Aftermarket Assassins Helix transforms your existing clutch kit setup. When paired with the AA S2 Clutch Kit, it upgrades your system to full S3 Clutch Kit performance levels. Riders seeking more aggressive acceleration and enhanced off-road responsiveness will appreciate the immediate difference this component delivers. Proper weight adjustment is recommended according to the S3 setup sheet for optimal results.
Designed to excel with tire sizes ranging from 32” to 37” and paddle tires from 30” to 33”, this helix is a must-have upgrade for riders running larger setups or demanding maximum performance from their Pro-R. Thanks to the Pro-R’s large ratio clutches, no additional high-load angle is required—making this the go-to performance helix for most terrain and riding conditions.
Installation is straightforward and only requires the AA Compression Tool #1. Backed by Aftermarket Assassins’ commitment to quality and innovation, this helix delivers measurable performance gains and long-term durability. If you’re ready to push your RZR Pro-R to the next level, the Aftermarket Assassins Custom Cut Helix (Part Number: 107-1072) is the upgrade your machine deserves.
