Ultimax Snowmobile Belt- 138-4400U4

This Ultimax PRO snowmobile belt, part number 138-4400U4, is built to give you better performance and a longer belt life on mid-horsepower snowmobiles. It's designed to work with your machine's clutches, featuring a thicker cross-section that increases the surface area where the belt meets 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 this belt is key to its strength and flexibility. It helps dissipate heat, which is important for handling the power of modern snowmobiles, and also aids in flexibility for improved performance. The belt is constructed with fiber-loaded rubber and strong aramid fiber cord, which grips the clutch effectively and maintains its performance without stretching over time. This is a fifth-generation belt, benefiting from decades of refinement and steady improvements in design and materials to ensure it runs cooler and handles the power output of today's machines.
