Product Details

The Dayco 5120788 Poly Rib Belt is a heavy-duty 5-rib serpentine belt engineered for reliable performance in automotive accessory drive systems. Designed as a direct OEM replacement, this belt delivers consistent power transfer to engine accessories including the alternator, power steering pump, air conditioning compressor, and water pump.

Dayco's Poly Rib belts are constructed with a high-strength, fiber-reinforced EPDM rubber compound that resists heat, oil, and ozone degradation—providing longer service life compared to traditional neoprene belts. The precision-molded rib profile ensures quiet, vibration-free operation and optimal contact with each pulley groove.

Key Features:

  • 5-Rib (PK) profile for smooth, efficient power transmission
  • EPDM rubber construction for superior heat, ozone, and abrasion resistance
  • Fiber-reinforced tensile cords for high load capacity and dimensional stability
  • OEM-quality fit — engineered to meet or exceed original equipment specifications
  • Quiet operation — precision rib geometry minimizes noise and vibration
  • Resistant to cracking, glazing, and premature wear

Dayco is a globally recognized leader in power transmission and fluid management products, trusted by OEM manufacturers and professional technicians worldwide. The 5120788 is a direct-fit replacement belt that installs without modification using standard hand tools.

Extremely Happy! Best price on the web, easy order tracking, if only all online orders from other sources were this easy. I ordered a component from another online retailer who showed parts "in stock" only to see my status as "sent to warehouse" and it was weeks. When Autoplicity shows "in stock" it really was and delivered right away.

Lowest price that i could find,fast shipping!!!!!<br>

It took exactly a week for the part to be shipped because the part came directly from the supplier. But the price was the lowest around.

I just received my order 7260 very quickly and it was as I had ordered............very easy to order and would do business with them again and I also will recommend them to others.

Better prices and even better service. Will do business with again.

The price was really good compared to other places I looked. They shipped my order the next day which was really nice as I needed the product ASAP. Thanks Autoplicity

Perfect item, fast shipment, great communication, and the best price.

Great communication, lowest price I could find anywhere, and quick shipping with a tracking number. What more could you ask for. 2nd time dealing with them and still impressed! order# 6935
