Description

The SP1 Defender Wearbar, part number WB-000-296, is engineered specifically for Polaris snowmobiles, including models from 2003 to 2006 such as the 700 SKS, 700 Switchback, 900 RMK, and 550 Trail RMK. Crafted with a 7/16 inch carbon steel host bar featuring a flat top design, this wearbar is built to prevent “bar roll” during aggressive cornering, ensuring reliable performance in challenging conditions. The carbide segments are made from high-quality yg13 tungsten, providing exceptional tensile strength and hardness to resist chipping and extend service life. The uniquely designed 90-degree angle of the carbides into the runner pockets creates larger cross-sectional areas compared to conventional designs, maximizing durability and support during rigorous use.
The 1-inch carbide segments allow for flexible movement of the ski without compromising carbide adhesion, contributing to overall stability and control. Each wearbar is precisely engineered and test-fitted to fit your specific Polaris model, making installation straightforward. Chamfered ends help reduce catching when backing up or unloading, enhancing maneuverability. Extended studs accommodate ski skins, offering added versatility for different snow conditions. All necessary fastening nuts, specifically nyloc nuts, are included to ensure secure attachment.
Both carbides and wearbars are finished with a black rust preventative coating to resist corrosion and weathering, while the hardweld contact area on the host bar increases longevity by adding depth and strength. Designed to be less damaging to concrete and asphalt surfaces, the SP1 Defender Wearbar offers a durable, reliable solution for snowmobile enthusiasts seeking enhanced performance and protection for their Polaris models.
