Dayco Top Cog V-Belts are designed for power transmission to vehicle accessory. Back in the early days of the fledgling automotive industry, Dayco was the first to develop the raw edge sidewall construction, which facilitates controlled slippage around pulleys. Raw edge construction is combined with Dayco's patented cogged top v belt design to ensure the top performance that today's vehicles and drivers demand. The Dayco Top Cog V-Belt delivers more flexibility, and increases airflow around the belt, so it runs cooler and lasts longer than most competitive belts. Three plies of neoprene impregnated fabric resist heat, oil, and grease, and a specially formulated treatment of the polyester cord provides the strength, stability, and reliability that are required of a "national brand" v-belt. Dayco Top Cog V-Belts meet or exceed SAE J636 and J637 specifications.
