Designed for high mileage multiple-accessory drivesthe Dayco® “W” profile belt (patent pending) is the most innovative advancement in multi-rib belt design in over 25 years. Developed through extensive laboratory and actual road mileage testing, this unique rib profile has been specifically Dayco® engineered to conform to high mileage, worn or misaligned drives without a sacrifice in quiet, long-lasting performance. The "W" profile cut into the tip of each rib makes the tip more flexible and eliminates belt chirp when the belt enters a worn or misalligned pulley. Constructed with Aramid reinforced EPDM compounds, the Dayco® “W” profile belt delivers more than OE required delivers the solution to troublesome drive problems. Dayco® Poly-Rib® Belts meet or exceed SAE J1459 and SAE J2432 specifications.
