QRS Float Mod

The KWI QRS Float is the ultimate solution for resolving the factory alignment flaws in Can-Am X3 CVT systems. If you’ve experienced hard shifting, a secondary clutch that spins at idle, or constant belt failures, chances are your clutch system is misaligned. This misalignment causes the belt to ride unevenly on the sheaves, leading to excessive heat, premature belt wear, and reduced performance.
Our QRS Float Mod addresses this by machining the secondary clutch to allow it to “float” on the shaft—letting it self-align with the primary during operation. This corrects misalignment under all load conditions, resulting in better power transfer, smoother shifting, and drastically improved belt life.
Every QRS Float package begins with a full inspection and precision sheave resurfacing to eliminate imperfections from wear and factory casting. Paired with our Big Roller Update, the QRS Float becomes the most effective way to restore consistency and maximize CVT performance in your Can-Am X3.
Overview
Whether you’re tackling dunes, rocks, trails, or mud, the QRS Float gives your Can-Am X3 the reliability and efficiency it needs. From smoother shifting and more responsive throttle feel to reduced belt temperatures and fewer failures, this mod is a must-have for serious riders.
Choose from four packages—Base, Plus, Pro, and Pro Aggressive—depending on your riding style and desired performance level. We also offer Standard and Fast Float service options to fit your timeline.

What is the Float Mod, and what does it do?
The Float Mod is a modification that offers several advantages:
- Increases wheel horsepower and accelerates your vehicle more quickly.
- Produces quieter clutches and maintains ultra-smooth shifting by eliminating warping and belt chatter.
- Lowers belt temperatures by resurfacing and recutting sheave angles for more efficient shifting and increased wheel horsepower.
- Fixes warped clutch sheaves and factory belt misalignment, common issues in X3 clutches that cause belt chatter, vibrations, power loss, and increased belt heat.
You have two options to consider:
- KWI Fast Float: Offers a 48-hour turnaround time.
- KWI Float Mod: Standard turnaround time is 10 days.
KWI has a proven solution used by X3 owners worldwide. They will true up your warped primary and secondary sheaves on their ultra-precision CNC lathe, re-cut the sheave angles on both your primary and secondary clutches, replace the secondary rollers with upgraded KWI rollers, set up your clutches to fully float and self-align at all RPMs, service your primary bearing, and replace any wearable or damaged parts (additional cost). Your clutches will be sent back ready to bolt on, and you can also purchase their clutch kit, which they will install during reassembly.

What could cause difficult shifting between gears (P, R, N, H, L) in my X3, and how can I address it?
Diagnosing the issue with your X3 properly is important to determine the best course of action. Here are a few possible causes for the hard shifting between gears:
Clutch misalignment: The belt could be touching or very close to one of the primary sheaves at idle due to a factory misalignment. This issue can sometimes be masked by the weak factory clutch calibration. To resolve this, you can have BRP replace the clutches under warranty or send your clutches to a specialist like KWI for the Full Float Mod, which will allow you to adjust the alignment and prevent future issues.
Damaged primary clutch bearing: If the bearing is not spinning smoothly or has seized on the shaft, it can drag the belt and spin the secondary, causing hard shifting. In this case, the bearing will need to be replaced.
Damaged or broken secondary clutch rollers: This can also cause hard shifting. If you send your clutches in for the Full Float Mod, upgraded rollers can be installed to prevent this issue. Alternatively, you can replace the rollers using parts from specialists like KWI.
If you have the KWI Float Mod verify all Float Mod spring, billet spacer, shims are installed correctly per the instructions below.
Secondary clutch grease or dirty gearbox shaft issue: If you have KWI Full Floating clutches and hard shifting occurs, it may be because the clutch is not sliding freely on the gearbox input shaft due to rust/dirt or a lack of grease. To address this, remove the clutch from the splined shaft, remove any and all rust, dirt and grease from the shaft, clean and re-grease the splines and shaft with good quality MOLY or CV grease and then reinstall.
PD Update: Additionally, if you're experiencing hard shifting issues, consider upgrading to the KWI PD Update. This update is specifically designed to address sticking problems in the PDrive clutch, ensuring smoother shifting and improved performance. Consult with a professional mechanic or contact KWI for more information on integrating the PD Update into your clutch system.
It's always a good idea to consult a professional mechanic to accurately diagnose and fix the issue. Proper maintenance of your vehicle's transmission and clutch system will help ensure smooth shifting and prolong the life of these components
