Ultimax Snowmobile Belt- 140-4748U4

Ultimax is known for making reliable snowmobile drive belts, and their PRO line is built for machines that need a little extra. This 140-4748U4 belt is designed for mid-horsepower snowmobiles, giving you that extra bit of performance and a longer lifespan out of your drive system. It's got a thicker cross-section than stock, which means more surface area making contact with your clutches. This translates to less slippage, especially across a wider range of speeds, so you get quicker acceleration when you need it.

The design includes cogs on both the top and bottom of the belt. This isn't just for looks; it gives the belt more strength and helps it dissipate heat better, which is important for handling the power from today's snowmobile engines. The construction uses fiber-loaded rubber combined with strong aramid fiber cords. This combination grips the clutch surfaces well and holds its shape without stretching over time, maintaining consistent performance. This is their fifth-generation belt design, meaning it's been refined over decades to offer steady improvements in how it works and how long it lasts.
