Description

The SP1 Defender Wearbar, part number WB-000-266, is engineered specifically for Polaris snowmobiles to enhance durability and performance. Crafted with a 7/16″ carbon steel host bar featuring a flat top design, it prevents “bar roll” during aggressive cornering, providing stability and control. The wearbar incorporates carbide segments made of YG13 tungsten, known for its exceptional tensile strength, hardness, and resistance to chipping, which significantly extends the lifespan of your wear components. The 90-degree angle of the carbide into the pocket of the runner creates large cross sections, offering improved strength and durability under demanding conditions.

Designed with flexibility in mind, the 1″ carbide segments allow for some flex in the ski without compromising the adhesion of the carbide, ensuring consistent performance over time. The wearbar is precisely engineered and test-fitted to fit your specific Polaris model for an easy installation process. Chamfered ends reduce catching when backing up or unloading, enhancing maneuverability. Extended studs enable the use of ski skins, adding versatility for different terrain and snow conditions.

All necessary fastening components, including Nyloc nuts, are included with the wearbar, making installation straightforward. The carbides and wearbars are finished with a black rust preventative coating to resist corrosion. Additionally, the hardweld contact area on the host bar provides increased depth and longevity, ensuring the wearbar withstands rigorous use. This design is less damaging to concrete and asphalt surfaces, making it suitable for various environments. Overall, the SP1 Defender Wearbar offers a reliable, durable solution that enhances your Polaris snowmobile’s performance and longevity.
