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