Got A Super Mountain Mod? Enter To Be A Rocky Mountain Snowmobile Expo EXTREME MACHINE!

For years, select western snowmobilers have built extreme machines that climb anything and go anywhere, all while looking, sounding and acting like nothing else on the planet.

These machines often include big power additions, exotic materials, customized ergos, lightweight components, mega-long tracks — the possibilities seem endless. And that’s before efforts to customize the look of the sled.

We’re celebrating these extreme mountain machines this year at the Progressive Insurance Rocky Mountain Snowmobile Expo in Denver, Colorado, and in the Backcountry section of Snow Goer magazine.

Do you have a machine you believe is worthy of being a Rocky Mountain Snowmobile Expo Extreme Machine? Send an e-mail to with a couple photos, and tell us the following:

  • What model your sled started its life as;
  • The specific mods done to the engine/drivetrain, track, chassis, suspension and elsewhere;
  • The estimated total investment;
  • Interesting facts or stories behind the build;
  • Any special shout-outs to people who helped you along the way.

Rocky Mountain Extreme MachineWe’ll select five Extreme Machines that will be featured at the Rocky Mountain Snowmobile Expo (October 12-13) for everybody to see — so even if you don’t have an Extreme Machine or if your sled doesn’t make the final cut, come and see the exciting creations that will be on display at this prestigious show. The honored sleds will also be featured in Snow Goer magazine, so you can read all about them, and the stories behind the builds and their owners.

Please note: The Extreme Machines program is directly tied to the Rocky Mountain Snowmobile Expo in Denver. Anybody can send in their information, but we’re specifically looking for people who are willing to bring their extreme sled to the Denver show to have it displayed and honored.

The show is produced by EPG Media LLC and the team at Snow Goer magazine and, in coordination with the Colorado Snowmobile Association. For details, visit
