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.
