Snowmobile ski runners, also called wear bars or skegs, play a critical role in how your snowmobile handles. They influence everything from cornering grip to steering effort. Choosing the right ones can mean the difference between a confident ride and an unstable one.
Whether you're cruising groomed trails, navigating icy terrain, or riding long distances, this guide will help you find the best ski runners for your sled, your conditions, and your style.
What Are Ski Runners and Why Are They Important?
Ski runners are steel bars mounted underneath your snowmobile’s skis. They serve three key functions:
• Protect the bottom of your skis from damage
• Grip the snow or ice thanks to embedded carbide inserts
• Steer the snowmobile by keeping it on a straight track, especially on hard-packed or rutted trails
They may seem simple, but these metal bars have a big impact on how you ride.
Ski Runner Shape, Width, and Carbide Length Explained
Runner Shapes: Round vs. Square vs. Dual
• Round runners: Smooth and easy to turn. Best for comfort and casual trail riding.
• Square runners: More grip and bite, but heavier to steer. Ideal for performance-focused riders.
• Dual runners: Two bars per ski that reduce darting. Perfect for rutted trails or riders seeking more stability.
Host Bar Widths: Small Changes, Big Impact
• 3/8" bars: Balanced control and effort
• 7/16" bars: Increased grip and steering resistance
• 1/2" bars: Common in aftermarket runners for aggressive use, but not typically found on OEM Ski-Doo models.
Carbide Length: What You Need to Know
• Shorter carbide (4"): Offers easier turning and lighter steering effort.
• Longer carbide (6–8"): Increases front-end grip and stability, especially on hard-packed snow or ice, but may require more effort.
Match carbide length to your terrain and style. More isn’t always better.
How to Choose Ski Runners for Your Riding Style
Riding Style Recommended Type
Casual trail riding Round runner, short carbide
Performance / aggressive Square runner, long carbide
Crossover / mixed terrain Dual or wide runner, medium carbide
Touring / comfort Round or adjustable runner
How to Stop a Snowmobile from Darting
Darting happens when your skis get pulled into ruts or grooves left by other sleds, causing a twitchy or unstable feel.
Tips to prevent darting:
• Use dual runners or a wider bar
• Increase your carbide length slightly
• Check your ski alignment
• Try adjustable skis like Ski-Doo’s Pilot TS
Ski-Doo’s Pilot TS: Adjustable Ski System for Any Condition
The Pilot TS is an exclusive Ski-Doo ski system that allows you to adjust how deep the ski runner penetrates the snow.
• Turn the knob to lower the runner for more bite on hardpack
• Raise it for lighter steering on soft snow
• 20 fine-tuned positions—no tools required
Ideal for drivers who want maximum control in all conditions.
When to Replace Your Ski Runners
Look for these wear signs:
• Flat spots or uneven wear
• Missing or heavily worn carbide
• Excessive bar thinning or edge loss
Always replace both runners at the same time to keep your steering balanced.
OEM VS Aftermarket Ski Runners
While aftermarket runners exist, genuine Ski-Doo runners offer:
• Perfect fit and compatibility with your sled
• Engineered handling and balance
• BRP-tested durability and performance
For long-term reliability and confidence, stick with OEM.
