Product Details

The Dayco 5040340 is a premium poly-rib serpentine belt engineered for high-mileage multiple-accessory drives in passenger cars and light-duty trucks. This 4-rib belt measures 34 inches in effective length with a width of 0.56 inches, designed to deliver reliable power transmission across multiple accessory components.

Advanced W Profile Design:

Developed through extensive laboratory and actual road mileage testing, this unique rib profile has been specifically engineered to conform to high mileage, worn or misaligned drives without sacrificing performance. The innovative W profile cut into each rib tip provides enhanced flexibility and helps eliminate belt noise in demanding conditions.

Key Features:

  • Aramid-reinforced EPDM compounds resist cracking and perform better in extreme temperature ranges
  • Multiple rib design provides better belt-to-pulley contact for less slippage, providing longer life than conventional V-belts
  • Meets SAE J1459 and SAE J2432 specifications
  • Industry number 4PK0865 for easy cross-referencing
  • Controlled slippage capability in shock load situations

This belt delivers OE-quality performance with enhanced durability for today's demanding drive systems, making it an excellent replacement choice for multiple-accessory applications.

I purchased an extend-a-truck on autoplicity. It was the best price on the Internet. Autoplicity beat amazon by approximately $30. I received a confirmation it shipped the following day.

Execellent retailer. Easy to buy from online. Got product quickly at a great price. I highly recommend!
