What makes this belt provide quicker acceleration?

The Ultimax PRO belt has a thicker cross-section that increases its surface area contact with the clutch. This reduces slippage, allowing for more direct power transfer and quicker acceleration across a broader speed range.

How does the cog design benefit the belt?

The cog design adds strength to the belt, helps dissipate heat which can shorten belt life, and maintains flexibility. This combination contributes to enhanced performance and increased lifespan.

What materials are used in this Ultimax snowmobile belt?

This belt is constructed with fiber-loaded rubber and strong aramid fiber cord. This combination ensures it grips the clutch effectively and maintains performance without stretching over time.

Product Details

When you're out on the snow, the last thing you want is a belt that can't keep up. This Ultimax PRO snowmobile belt is built to handle the demands of mid-horsepower sleds, ensuring you get reliable power transfer when you need it most. It's designed to grip the clutch better, which means less wasted energy and more responsive acceleration.

What sets this belt apart is its thicker cross-section. This increases the surface area that contacts the clutch, reducing slippage across a wider range of speeds. The cog design isn't just for looks; it adds strength, helps dissipate heat that can shorten belt life, and keeps the belt flexible. This combination leads to improved performance and a longer lifespan, especially with today's more powerful snowmobiles.

Built with fiber-loaded rubber and strong aramid fiber cord, this belt is made to resist stretching and maintain its performance over time. It's a fifth-generation design, meaning it's benefited from decades of refinement and steady improvements. You can expect it to run cooler, handle the power your machine puts out, and provide consistent grip.
