Ultimax Snowmobile Belt- 125-4320U4

The Ultimax PRO snowmobile belt uses a fiber-loaded rubber compound reinforced with strong aramid fiber cord. This construction helps the belt grip the clutch effectively and maintain its performance without stretching over time. It's built with a thicker cross-section compared to stock belts, which increases the surface area that contacts the clutch. This means less slippage across a wider range of speeds, leading to quicker acceleration when you need it most.

This is a fifth-generation belt design, benefiting from decades of refinement and steady improvements. The top and bottom cog design offers greater cord support, which helps handle the power output of modern snowmobiles. This design also helps the belt run cooler, dissipating heat more effectively and aiding flexibility. All these factors contribute to enhanced performance and an increased lifespan for the belt, making it a solid option for mid-horsepower snowmobiles.
