For general service machines, air-cooled under 500cc, choose Ultimax 2 snowmobile belts. Its notable strength and tensioning suits lower horsepower machines. This belt powers more snowmobiles than any other aftermarket drive belt in the world! Added flexibility of the new double cog design runs cooler and lasts longer. Each belt meets exacting tolerances, using only the best rubber compounds and a tough Aramax cord. Expect longer life on virtually all general service machines.
