Ultimax Snowmobile Belt- 144-4340U4

This is the Ultimax PRO snowmobile belt, part number 144-4340U4. It's built with a fiber-loaded rubber compound and strong aramid fiber cords, which help it grip the clutch effectively and maintain its performance without stretching over time. This belt is designed to handle the demands of mid-horsepower snowmobiles, offering a good balance of performance and longevity.

The Ultimax PRO belt has an updated, thicker cross-section compared to older designs. This increased surface area means less slippage when engaging with the clutch, translating to quicker acceleration across a wider range of speeds. The cog design on both the top and bottom of the belt not only adds strength and flexibility, helping it dissipate heat effectively, but also provides better cord support for increased output. This means it can handle the power from today's snowmobile engines while running cooler, which contributes to its enhanced performance and increased lifespan.
