Dayco approaches the market differently from most of its competition, believing that one serpentine belt construction will not perform best with all applications.
Built for passenger cars and light-duty trucks, Dayco’s extensive line of Poly Rib serpentine belts are engineered for high mileage, demanding drives found in today’s vehicles. As the manufacturer of the first original equipment multi-ribbed serpentine belt, Dayco’s commitment to automotive product excellence and innovation is unwavering.
The Dayco Poly Rib W Profile serpentine belt is the most innovative advancement in serpentine belt design in more than 30 years. Developed through extensive laboratory and actual road mileage testing, this unique rib profile EPDM belt has been engineered to conform to high mileage, worn or misaligned drives and help eliminate noisy belt conditions.
Constructed with aramid-reinforced EPDM compounds, the Dayco W Poly Rib serpentine belt delivers more than just OE-required quality. It delivers the solution to troublesome drive problems.
Dayco manufactures other serpentine belt constructions for application-specific belt drive systems, such as the ela® stretch belt, special deep rib belts for certain import applications, Linear Groove Technology belts and double-sided belts.
- ela Stretch belt – Designed for direct replacement on accessory drives requiring stretch-type belts, Dayco ela belts are specifically designed for two- to four-point drives where the elastic belt design maintains constant tension on the drive.
- Deep Rib belt – Dayco discovered that certain import applications perform quietest when the rib depth of the serpentine belt is increased. Dayco added layers of material, increasing the rib depth of the Deep Rib belt, resulting in the best drive belt option for specific import vehicle applications.
- Double-sided belt– Designed for multiple accessory drives that require the transmission of power from both sides of the belt. The Double-Sided belt, which Dayco introduced to the automotive aftermarket, features a construction that uses a highly fiber-loaded compound on both sides of the belt to maximize load carrying requirements while minimizing pulley misalignment noise.
