Subaru WRX 2004, Poly Rib™ W Profile Serpentine Belt by Dayco®. Material: Fabric. Compared to any other belt on the market, this belt provides better belt-to-pulley contact thus reducing slippage and noise thanks to its multiple rib W profile design, while its transverse groove design ensures cooler running and reduced rib cracking. Built with aramid reinforced EPDM compounds, this product provides more than just OE required quality for quiet, reliable, and lasting performance, it’s the perfect belt for imperfect drives.

Accessory drive belts wind their way around such components as the power steering pump, water pump, air conditioning compressor, and alternator propelling them when the engine is running. While older vehicles used separate V-belts for each component, newer vehicles have a single serpentine belt to drive them all. Dayco approaches the market differently from most of its competition, believing that one serpentine belt construction will not perform best with all applications.
Dayco Poly Rib W profile serpentine belt is one of the most innovative advancements in serpentine belt design in over 25 years. This application-specific component was developed though both exhaustive laboratory and road mileage testing to ensure a precise fit, quiet, and long-lasting performance even on vehicles with worn and misaligned accessory drives. Designed for power transmission on multiple-accessory drives, this product features a multiple rib design with innovative W profile that provides better belt-to-pulley contact reducing slippage and noise thus delivering longer life and quieter operation compared to a standard belt.
Built with a transverse groove design, the belt runs cooler and reduces rib cracking while providing increased flexibility in both normal and backside bending. Made with aramid reinforced EPDM (ethylene propylene diene monomer (M-class) rubber) compounds, the product provides not only more than just OE required quality but also maximum load-carrying capability and noise-free performance delivering the solution to imperfect drives.
Since 1905, Dayco has been a leader in the automotive parts manufacturing industry. During the early 1900s, Dayco was the first and only company manufacturing the airless tire. By the 1920s, the company had a robust tire manufacturing process in Dayton, Ohio for cars, large trucks and buses. From its founding to today, the company has followed its primary business strategy to anticipate and satisfy all the needs and requirements of its customers by providing innovative, quality, and durable products. Today its wide product line includes belts, tensioners, pulleys and hydraulics equipment for the automotive, construction, trucking, ATV, agricultural, snowmobile, and industrial markets.
