What's a snowmobile ski runner?

Runners (also called skags or wear bars) are hardened steel and carbide bars bolted to the bottom of your skis. They bite into ice and packed snow for steering. Runners wear out faster than skis themselves.

How often should I replace ski runners?

Every 1–2 seasons of regular riding, or sooner on icy and rocky conditions. When the carbide is worn flush with the ski, replace immediately — running bare skis destroys the ski itself.

Aggressive runners or mild runners?

Aggressive (longer carbide, deeper bite) for hardpack and ice — bites better but causes darting. Mild (shorter, less aggressive) for powder and mixed conditions — easier steering, less darting. Match to your typical riding.

What's ski darting and how do I fix it?

Darting is when your ski follows ruts and grooves in the trail, pulling the bars side-to-side. Caused by overly aggressive carbides on a hard-packed trail. Solution: shorter or less aggressive carbides, or different ski stance.

Are aftermarket ski runners better than OEM?

Aftermarket runners often offer wider carbide selection, better-quality steel, and replaceable carbide tips. Brands like Stud Boy and Woody's are widely respected. OEM is fine but limits the upgrade path.
