The Dayco Serpentine Belt keeps several engine accessories turning from one compact drive while standing up to the heat and constant flexing that wear belts down. Made from aramid-reinforced EPDM, this Dayco 5080840 belt stays flexible around repeated pulley bends while resisting stretch under tension. The reinforced EPDM body can hold its shape under changing loads, helping the belt grip the pulleys consistently with less noise and vibration. Its eight-rib profile and 84.06-inch effective length are the final fit details to match to the existing drive.
