SnowTracker Semi-Aggressive Runners | Polaris

Improve your riding experience with a semi-aggressive SnowTracker kit, with the SELF-SHARPENING 6 inch carbide runners and with inverse “U” correctors. You will experience a smooth and satisfying steering.

Self-sharpening happens when the steel of the runner wears down (exposing the carbide), the same as when you sharpen a lead pencil. Since the carbide is harder, it wears less and the steel on carbide sides wear a little more. This is espacially so, when you cross roads and gravelly or paved areas. The runners always sharpens itself as you ride. The runner always for better control on ice and hard packed trails. The runner also lasts much longer than standard carbides due to the length of the carbide in the runner (saving money, less replacements, more security).
