Ultimax Snowmobile Belt- 138-4432U4

This is the Ultimax PRO snowmobile belt, part number 138-4432U4. It's built to give mid-horsepower snowmobiles the best performance and longest belt life. The PRO belt has a thicker cross-section compared to standard belts, which increases the surface area that contacts the clutch. This means you'll experience less slippage across a wider range of speeds, leading to quicker acceleration when you need it.

The cog design on both the top and bottom of the belt helps dissipate heat and allows for better flexibility, all while providing strength. This updated design helps the belt handle the power from today's snowmobiles and contributes to an increased lifespan. It's made with fiber-loaded rubber and strong aramid fiber cord for a grip that maintains performance without stretching over time.
