Big Thunder Nitrous Systems is the leader in snowmobile nitrous technology. We offer the most complete and the most powerful nitrous systems available for trail or race applications.

We also provide other performance products for Arctic Cat and Skidoo snowmobiles including clutch kits, pipe mods, aftermarket silencers, and porting.

We are adding products to the site as quickly as we can test them on our own snowmobiles! If the parts won't add power we won't sell them! Check back often to see what we are testing and what else is available for your sled.

Big Thunder Performance provides customers with safe, reliable nitrous systems and performance products for snowmobiles.

We would be happy to assist you with your product selection and help you solve any technical problems.
