Clutch kit for 22~2020 G4 x 850 x 3" (three inch track) with 990 low elevation ramps.  This kit can be used from sea level to 13000 feet. 

This is you...
You are standing looking at the hill, that constantly gets snow.  For most sleds making that hill is an accomplishment.  Yesterday it was unbeatable by you.  A few more mph track speed and I know I could do it.  But that was yesterday. 

Youll make that hill today because especially for you, we made this kit.  Today you stand at that hill with the clutch kit designed to give more than a few mph track speed  youll see at least 3.  In every area you go to there is a hill like that and when you beat it, youll find it being beaten with the help of this clutch kit.

  • In 5 minutes, a quick tune with the change of a bolt and spacer.
  • Cooler clutch and belt temperature
  • Smoothest engagement
  • Quicker backshift
  • Strongest engine braking
  • More track speed
  • Pulls hard to the finish.

You made it...


This is the strongest engine braking I've ever felt. 

A test guy said to me "I could stand up and drink a coffee coming down this hill haha". 

Opposite of that, crack the throttle and BANG....7900~8000 rpms, hang on. 

The kit digs deep, pulling out all the muscles from the engine.  It has the ability to make them useful not only wherever, but however you run your sled.

Tight connection between your thumb and snow.  Drive the clutching as smart as you want.  A tree rider's delight.

Throttle control
Feather smooth engagement for slow, wrong foot forward.  The handlebars dont surge, tugging on your hands.  After you made it, blip the throttle, time it right, do a victory wheelie.  You'll burst more track speed for the next climb.

Pulls hard
When you want to drive more aggressive, the feeling is like having a gigantic hand on the front bumper, pulling you up even the steepest hill. "woo hoo" and then its holding the sled back with strong engine braking coming down.

When you need the power to overtake your buddy, there is more power on tap to speed up and pass.  30mph side by side breaking fresh snow, full throttle, pull away strong to the finish.

Good mileage
Drive the clutch kit with the same fuel economy as stock clutching, most times even better.  With the low revving at part throttle, high torque feature when you need to drive for fuel economy on the way out >> Drive it gently and you will be rewarded with lower fuel consumption at part throttle, arriving back at the trailer.

There is more engine power under your thumb, just waiting to be used.
