Koronis 515-427 Snowmobile Carbide Wear Bar Runners with Stud Mount

The Koronis 515-427 S/D Hard Bar Runners deliver superior durability for snowmobile skis through advanced carbide construction. These wear bars feature a 1/8-inch high bead of carbon, high chrome alloy filler material welded along the entire length of the bar, providing exceptional resistance to abrasive wear on ice, hardpack, and rough trail conditions.

Key Features:

• High chrome carbide alloy construction provides 3 to 5 times the lifespan of standard wear bars
• 1/8-inch raised carbide bead welded continuously along bar length for maximum wear resistance
• 1-inch stud length designed for easier installation with ski skins
• Stud-mount (S/D) design for secure attachment to snowmobile skis
• Premium hard surface material maintains edge sharpness and steering control throughout extended use

These hard bar runners are engineered to withstand the demanding conditions of aggressive snowmobile riding while reducing replacement frequency and maintenance costs. The extended stud length simplifies installation and ensures compatibility with aftermarket ski skins.
