Drive Belts Vee

Dayco was the first to develop the raw edge sidewall construction V-belt, which facilitated controlled slippage around pulleys.

Top Cog® V-belts
Raw edge construction is combined with the Dayco patented cogged top 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 competitors' V-belts. Three plies of neoprene impregnated fabric resist heat, oil, and grease, and a specially formulated treatment of the polyester cord provides strength, stability, and reliability.

Gold Label V-belts
Top Cog® Gold Label® V-belts – the gold standard of performance - are the industry leader in truck and heavy duty applications. Designed with greater absorbance to shock load that is prevalent in diesel engines, Gold Label® has a higher resistance to heat, oil, grease and contaminants than any other V-belt on the market.
