Clutch Kits-FX Nytro All Models

Low engagement doesn’t mean low power anymore!

The FX Nytro Torque Monster Clutch Kits are custom calibrated for all models. The FX Base, FX RTX, FX XTX and FX MTX.  These clutch kits are tailored per customer (no cookie cutter set-ups) to take the guess work out of the picture. Designed by SBM to improve the FX at engagement, low, mid, throttle response, engine braking and top speed. Lets talk about engagement. We are clamping the belt harder @ the primary clutch (the small pulley) to reduce belt slip, gain belt longevity and widen the gear ratio. Have you noticed that loading and unloading the sled is difficult because it wants to spin the track and leap forward or backwards uncontrollably. Even backing up is hard and sometimes problematic. Have you also experienced having to blip the throttle a bunch of times to negotiate a turn at lower speeds? This is where Schmidt Bros Motorsports comes in. Our clutch kits were developed for each model specifically. This four stroke engine has over 71 ft lbs of torque @ 3,500 rpm’s, so why would you need to engage @ 3,800 – 4,200 rpm’s. You won’t believe how well you will be able to maneuver at lower speeds with the addition of the lower 2,900 rpm engagement. Now lets talk mid-range arm stretch. Basically all models over-rev from the factory and this means, you are above the peak torque and hp of the engine. A stock sleds tach will generally read 9,100 to 9,400 rpm’s with the throttle pegged at mid speeds which is about 400 to 700 rpm’s above peak hp. If you think your Nytro is fast now, try keeping it in the (CAMSHAFT) all the way to top end. Talk about torque monster. A big plus from this set up will be lower rpm’s. This translates into better fuel mileage across the board and broad torque in the mid-range. Get control of your Nytro and make a night and day difference and harness the awesome torque that puts a smile on your face so that you can put it where it belongs, the snow. Easily installed at home (No puller needed) and every kit comes with a Full Quiet Kit.
FX-Nytro Comfort Clutch Kit: The Nytro Comfort Clutch kit is for those who don’t like the higher engagement in the Nytro models. This clutch kit lowers the engagement for smooth take-offs and maneuvering. You will experience less track spin, jumpiness, and aggressive backshift (the “thrown forward” feeling). Don’t be fooled by the word “Comfort”. With this kit you will see improved mileage, increased power to the ground, and a comfortable/controlled use of reverse. Includes a primary spring, rollers and a full quiet kit. “Comfort” does not mean slow. Along with an extended top end, you will also get:
  • Smooth take-offs
  • No trenching out
  • Awesome low speed maneuvering
  • Less track spin
  • Comfortable/controlled use of reverse
  • Improved mileage
  • Increased power to the ground
  • Smooth consistent cornering
  • Reduced inside ski lift

Fx-Nytro Stage II: The Stage II clutch kit provides all the benefits of the Comfort Clutch Kit while adding a ton of extra throttle response and pop across the entire range of the Nytro. Take your Ntyro to the next level of performance where the stock helix can’t take you. Kit includes a primary spring, full quiet kit, rollers, calibrated tuning rivet weight combo for the stock flyweights, over driven progressive secondary helix and a secondray spring with out the coil bind issue.

**The 08-09 MTX was geared too high from the factory for proper higher elevation performance. That’s why an optional higher elevation gearing kit w/ oil is available for $59.99.

Already Clutched? Supercharged? Turbocharged? Are you trenching out on take-off? By adding our low engagement primary spring we can lower your engagement by 1000 RPM. This spring is for heavier weighted primary clutches. Includes a Full Quiet Kit to take that annoying rattling noise away by 80%.
