Ultimax® Pro Belts by Timken

Ultimax PRO delivers optimum performance and belt life to mid-horsepower snowmobiles. Engineered specifically for your machine, Ultimax PRO features a thicker cross section so more surface area contacts the clutch. This means less slippage over a broader speed range for quicker acceleration. The cog design provides strength, dissipates heat and aids flexibility delivering enhanced performance and longer belt life.

One Year Warranty. Proudly made in the U.S.A. 


  • Designed for modern mid-power snowmobiles

  • Top and bottom cog give greater cord support – meaning greater power capability – without sacrificing flexibility

  • Ultimax PRO runs cooler to better handle the power demands of today’s machines

  • Fifth generation belt with decades of refinement and steady improvements

Materials and Manufacturing

  • Fiber-loaded rubber designed to grip the clutches and to stay that way over the life of the belt

  • Strong and stable aramid cord for zero stretch and maximum tensile strength

  • Built with modern methods to reduce variability and eliminate “classic” failure modes


  • Every Ultimax PRO belt is manufactured using new processes that reduce dimensional variation so every belt performs consistently

  • Dimensions match OE in cord length and width, meaning your sled will shift like new  

  • Dimensions are held to tighter tolerances than OE belts

Decades of advancement and experience are built into every Ultimax belt. Ultimax PRO is designed with high-strength materials to handle every riding style from ditch-banging, to deep powder to trail riding. Over a million miles a year of documented field testing ensure that Ultimax belts stay ahead of the pack in value and performance.
