SPI D0664640 Slasher Six60 Snowmobile Carbide Ski Runners for Yamaha

The SPI Slasher Six60 Carbide Ski Runners (Part# D0664640) are a performance-engineered replacement runner set designed specifically for Yamaha snowmobiles. Built for riders who demand superior steering control and long-lasting durability, these runners deliver aggressive cornering performance and exceptional resistance to wear and impact damage.

Slasher Six60 Runner Style:

• Features 6 inches of 60-degree tungsten carbide engineered for improved handling and performance cornering
• 1.5-inch carbide wear pads at the front and rear with hardweld material in between for maximum contact and durability
• Recommended for riders running a studded track

Host Bar Construction:

• 7/16-inch carbon steel host bar with a flat-top profile to prevent bar roll during aggressive cornering
• Carbides are machined at a 90-degree angle into the pocket of the runner, creating larger cross-sections compared to competing designs
• Diamond-shaped carbides set deeper into the host bar for greater surface contact adhesion, making them less susceptible to side-impact failure from rocks or gravel

Carbide Quality & Durability:

• Carbides manufactured from YG13 tungsten for ultimate tensile strength, extreme hardness, and resistance to chipping
• 1-inch carbide segments allow for ski flex without compromising carbide adhesion
• All carbides and wearbars finished in a black rust-preventative coating
• Chamfered ends to reduce catching when backing up or unloading the sled

Fit & Installation:

• Precision engineered and test-fitted for exact ski fitment and straightforward installation
• Extended studs to accommodate ski skins
• All necessary nyloc fastening nuts included
