Pit Stop USA is The Online Motorsports Superstore! Since 1905, Dayco has provided belts for the automotive industry. DaycoA Top CogA 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 Daycoas patented cogged top design to ensure the top performance that todayas 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 anational branda v-belt. DaycoA Top CogA V-Belts meet or exceed SAE J636 and J637 specifications. We feature DaycoA belts like DaycoA Top CogA V-Belts and DaycoA Gilmer Drive Belts at low everyday prices!
