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.

Developed for higher performing ATV and UTV applications with up to 120HP, moderate performance upgrades and engines up to 800cc.

Dayco POWER XTX ATV Belts are constructed with specially formulated, high-temperature polychloroprene with an aramid fibre reinforcement for increased horsepower capacity and more responsive engine braking during deceleration. This belt is proven reliable at well over 12,000 RPMs, for faster, more consistent throttle response and improved durability. The Dayco POWER XTX ATV Belt’s breakthrough design features deeper cogs on top and rounded cogs on the bottom for ultimate flexibility, longer belt life and cooler running temperatures compared to leading competitors.
