Dayco Belts, Hoses, Tensioners & Pulleys

Poly Rib™ Dual Sided Serpentine Belt by Dayco®. When the transmission of power from both sides of the belt is required, choose this dual-sided serpentine belt specially constructed for multiple accessory drives. With highly fiber-loaded compound on both sides, this product ensures superior durability for lasting service life, while minimizing pulley misalignment noise.



  • Designed for power transmission on multiple-accessory drives
  • Transmits power from both sides of the belt
  • Direct OE replacement
  • Provides quiet performance
  • Delivers more than just OE required quality
  • Aramid reinforced EPDM compounds for maximum load-carrying capability and prolonged service life
  • Multiple rib design provides better belt-to-pulley contact to reduce slippage
  • Transverse groove design for cooler running and reduced rib cracking
  • Highly fiber-loaded compound on both sides for maximum durability and minimal pulley misalignment noise
  • Meets or exceeds SAE J636 and J637 specifications

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.

This application-specific double-sided belt is specially designed for multiple accessory drives where the transmission of power from both sides of the belt is required. This product features the multiple rib design with straight rib profile that provides better belt-to-pulley contact reducing slippage thus delivering longer life compared to a conventional V-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. Thanks to its highly fiber-loaded compound on both sides, the product dramatically increases load carrying requirements while reducing pulley misalignment noise. This application-specific belt is made with aramid reinforced EPDM (ethylene propylene diene monomer (M-class) rubber) compounds that ensures more than just OE required quality and superior durability for lasting service life.

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.
