This kit includes the OEM Can-Am helix, OEM Can-Am spring, and MCB's improved impact-resistant rollers — a direct replacement for models that originally came with, or have been tuned to, 185-205HP.
| Model | Notes |
|---|---|
| Maverick X3 RR | 195HP — this is the correct stock angle |
| Maverick X3 DS, R, XRS, XDS | When tuned to 185-210HP |
| Defender HD9 / HD10 | When tuned to higher HP than stock |
This is also a great value if you simply need to replace your rollers and helix after a roller failure damaged the helix — a common failure point on higher-HP applications running worn stock components.
Many other helix angles are available for custom applications. MCB can custom build a clutch kit specific to your exact year, model, tire size, riding style, and modifications — understanding what helix angle, spring rate, and flyweight mass to run based on your setup. Proper calibration reduces load on the motor, clutches, and belt, significantly improving longevity after modifications like larger tires or added HP.
Real-world example: a farmer in Montana running a Defender HD10 at 8,500 ft elevation with 33" tires, using the machine primarily for towing heavy loads and plowing snow, puts extreme load on clutches and a belt originally calibrated for 0-4,500 ft elevation and general trail use. MCB can calibrate the correct helix angle, spring rate, and weight combination to significantly reduce that load and extend component life.
