Here’s where you’re going….

You made it…

iBackshift owners say

  • I love the smooth engagement to; feather the track to get unstuck.
  • Its the strongest; engine braking I’ve ever felt.
  • “I could stand up and drink a coffee coming down this hill haha”.
  • Tight connection between my thumb and snow.
  • Love how it pulls hard just like your older kits
  • Loved it on my 600 and now this 850, whoa.
  • Each time I order a new sled; this is always my first purchase. I love the Backshift.
  • Finally got snow and have a few rides on my clutch kit! Performs great, great power, love the Backshift. The engine braking is weird to me and definitely something to get used to.
  • My sled is not abruptly annoying on the bottom end anymore
  • My wife loves the clutching now
  • BANG….8 grand, hang on.

Throttle control

Feather smooth engagement for slow, wrong foot forward. The handlebars dont surge, tugging on your hands. After that, you made it, blip the throttle, time it right, do a victory wheelie.

Pulls hard

Full throttle, 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.
In conculusion, when you need the power to overtake your buddy, there is more power on tap to speed up and pass. 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 be rewarded with lower fuel consumption at part throttle….arrive back at the trailer.


Above all, there is more engine power under your thumb, waiting to be used. And….I promise you’re going to get stuck !

On clutch kitting – The best way for me personally to make a clutch kit, is still doing old fashioned side by side testing. In addition, it is the only way I’ve ever known that has worked for me. Part of the help is having test riders, just as obsessed at riding and testing. Generally, they too are obsessed with this craft. When you are obsessed with what you do, you get better at it.

The key to making a great clutch kit is toiling away, making someone else’s clutch kit. For this purpose, I rather the sled owner guide me on what to build for them to start out to run in their sled.

This entails me to be in a position where people want you to help guide them on what they need. For that reason, I listen and understand what needs they’re trying to achieve. Learning of how much of a problem or opportunity tuning presents is the beginning of the kit creation. This sometimes is difficult for me because some who know me say I have a short attention span. Haha

Umm…you think after 29 years, I woulda learned how not to blow up an engine. Really, I should just stick to clutching.

To me this isn’t a job. Furthermore, iBackshift is a creative space for tuning that I can stay in, and get better at, while others are fighting it out on a spinning merry-go-round of retail death.

Thanks dad…
