Our belts are made by one of the largest timing belt manufacterers in the world. The combination of the neoprene body and kevlar reinforcement provides the highest level of strength, durability, and longevity possible. In fact, our belts use the same kevlar webbing that is used in Top Fuel Dragster Supercharger belts! Not sure what this means? It means these belts are CRAZY strong.
