The Dayco Double Cogged Accessory Drive Belt for Ford is designed to provide strength, stability and dependability. It is made from neoprene impregnated cloth with three plies that resist heat, oil and grease. The polyester cord is specially treated to provide extra strength and stability. This belt also increases airflow around the belt, allowing it to run cooler and longer. It complies with SAE J636 and J637 requirements and allows for more flexibility.
