Product Details

This is the Ultimax PRO snowmobile belt, part number 144-4640U4. It's built to give you better performance and a longer life on mid-horsepower snowmobiles. The PRO belt has a thicker cross-section compared to stock, which means more surface area contact with your clutch. This helps reduce slippage, especially across a wider range of speeds, leading to quicker acceleration when you need it.

The cog design on this belt is key to its performance. It adds strength, helps dissipate heat that builds up during operation, and keeps the belt flexible. This combination means you get improved performance and the belt lasts longer, handling the power demands of modern snowmobiles. It's constructed with fiber-loaded rubber and strong aramid fiber cords, which grip the clutch effectively and resist stretching, maintaining consistent performance over time.

This is the fifth generation of this belt design, benefiting from decades of refinement and steady improvements. It's made to run cooler, which is important for handling the power output of today's machines. The top and bottom cogs offer better support for the cords inside the belt, allowing for increased output.
