Your Ski-Doo or Lynx clutch package left the factory tuned to survive stock power, turbo power, cold starts, warm starts, and every rider in between — which means it wasn't tuned specifically for any of them. Ibexx builds its Etec 850 Stage 2 clutch kits off one shared platform, but tunes each one differently depending on what's under your hood: naturally aspirated Etec 850s get a lower-engagement Blue Series setup with a secondary spring for smoother power delivery, Gen 4 Factory Turbo units get that same efficient Blue Series profile matched to the G4/G5 platform, and Gen 5 Factory Turbo units — built for higher horsepower — step up to the more aggressive Red Series weights. Same core hardware, three different tunes, so the power you're actually making gets to the track instead of getting lost in a compromise.
Why Your Ski-Doo/Lynx Stock Clutching Holds You Back
Factory clutch setups are built to handle every rider and every condition a sled might see, which means the flyweights, primary spring, and helix are all tuned conservatively. That's fine for covering warranty claims, but it means sluggish backshifting, flat throttle response, and a clutch that's holding your engine back instead of working with it — whether you're running a naturally aspirated 850 or a Factory Turbo.
Ibexx's Advanced Profile Fly Weights are engineered specifically around how your Etec 850 makes power, not a generic average of every sled on the trail. Each kit pairs the flyweights with a matched primary spring, helix, bushings, and magnets so the whole clutch works as one tuned system instead of a collection of stock parts.

What Makes It Different |
| Ski-Doo Etec 850 N.A Stage 2 Clutch Kit |
Naturally aspirated (non-turbo) Etec 850 riders who want a more responsive, lower-effort engagement |
Enhanced Blue Series flyweights with a lower engagement threshold, plus the only kit of the three to include a secondary spring |
| Gen 4 Ski-Doo E-TEC 850 Factory Turbo Stage 2 Clutch Kit |
Gen 4 (G4) Ski-Doo Etec Factory Turbo riders |
Blue Series flyweights — among the lightest available, with an aggressive ramp built to leverage the efficiency of the G4/G5 platform and build boost faster |
| Gen 5 Ski-Doo 850 E-Tec Factory Turbo Clutch Kit |
Gen 5 (G5) Factory Turbo riders running higher horsepower |
The 2nd Generation turbo kit, upgraded to Red Series flyweights with better engagement and a more aggressive shift profile than Blue Series |
Every kit above uses the same 20g of total adjustability per weight, via included .85g and 1.7g magnets, so you can fine-tune engagement and backshift feel after install rather than living with a single fixed setup.
Frequently Asked Questions
How do I know if I have a naturally aspirated or Factory Turbo Etec 850?
The N.A. Stage 2 kit is built for the standard, non-turbo Etec 850. If your sled came with a Factory Turbo option, you'll want the Gen 4 or Gen 5 turbo kit instead — Gen 5 units running higher horsepower should step up to the Red Series-equipped Gen 5 kit rather than the Blue Series Gen 4 kit. If you're not sure which generation your turbo platform is, check your sled's documentation or reach out before ordering.
What's actually different between the Blue Series and Red Series flyweights?
Both are described as among the lightest flyweights available, built with an aggressive ramp to build boost faster. Blue Series weights (used in the N.A. and Gen 4 Turbo kits) have a lower engagement threshold while still delivering an assertive shift. Red Series weights (used in the Gen 5 Turbo kit) are the newer, updated profile with better engagement and a more aggressive shift, aimed at higher-horsepower turbo setups.
Can I install this myself?
Most Ibexx clutch kits are a bolt-in job for anyone comfortable with basic wrenching. A primary clutch puller and spring compression tool make the job significantly easier — both available in our Ski-Doo tools collection.
Does this kit fit any specific model year of my Ski-Doo or Lynx?
These kits are matched to platform and engine configuration — N.A. Etec 850, Gen 4 Factory Turbo, or Gen 5 Factory Turbo — rather than a specific model year. If you're unsure which platform your sled falls under, contact us and we'll help confirm fitment before you order.
Built for Your Ski-Doo/Lynx, Not the Lowest Common Denominator
Every kit above uses Ibexx's Advanced Profile flyweight design paired with a matched primary spring, helix, bushings, and magnets — tuned to your specific engine configuration rather than a one-size-fits-all average. Not sure whether you're running N.A., Gen 4, or Gen 5 Factory Turbo? Contact us and we'll help you pick the right kit.
