Description

The SP1 Defender Wearbar S D (Part WB-000-476) is designed specifically for select Ski-Doo models including the Alpine II, Nordik, and Tundra series from 1990 to 1995. Crafted with a 7/16-inch carbon steel host bar, it features a flat top to prevent bar roll during aggressive cornering, providing enhanced stability and control. The wearbar utilizes high-quality YG13 tungsten carbides with a 90-degree angle into the pocket of the runners, ensuring large cross sections for increased strength and durability. This design minimizes chipping and extends the lifespan of the wearbar, making it ideal for demanding snowmobile conditions. The 1-inch carbide segments allow some flex in the ski without compromising carbide adhesion, ensuring consistent performance over time. Engineered and precisely test-fitted for easy installation, the wearbar includes chamfered ends to reduce catching when backing up or unloading. Extended studs accommodate ski skins, and all necessary Nyloc nuts are included for secure mounting. The carbides and wearbars are finished with a black rust preventative coating, resisting corrosion and maintaining appearance. Hardweld contact areas on the host bar provide additional depth, increasing longevity while reducing damage to concrete and asphalt surfaces. Whether tackling icy terrain or rough trails, this wearbar offers a reliable, durable solution for your Ski-Doo snowmobile, combining advanced engineering with ease of installation for optimal performance.
