The Dayco® Double Angle V-Belt is designed for serpentine and reversing drives, transmitting power from either side of the belt. Polyester cords and a durable cotton/polyester cover delivers maximum strength and length stability, while ensuring resistance to heat, ozone, grease, oil and dirt. Specially formulated core compounding provides for long life and high horsepower capabilities. This belt flexes equally well in either direction and provides natural wedging action on both sides for maximum power.
