Product Details

The Dayco 5120873 is a heavy-duty 12-rib poly rib serpentine belt designed for demanding automotive and commercial vehicle applications. This premium belt features an effective length of 87.25 inches with 12 raised ribs running the length of the belt, providing superior grip and power transmission for multi-accessory drive systems.

Key Specifications:

  • Outside Length: 87.875 inches (87-7/8 in)
  • Number of Ribs: 12

Construction and Performance:

Constructed with aramid-reinforced EPDM compounds, this serpentine belt delivers exceptional durability and temperature resistance.

Backed by Dayco's century-plus reputation for quality and innovation in belt manufacturing, this serpentine belt is engineered to meet or exceed original equipment specifications for reliable, long-lasting performance.

Ordered exactly what I needed, the price was good and received the part very quickly.

I ordered a new latch for my center console and it fit perfectly. I could have bought it locally but the local store didn't have it in stock. I figured if it had to be ordered I could order it sent to my house.

Autoplicity provides great service and fast delivery!

Easy and you had what I needed.

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.

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.

Let you know after I get my product I have received my goods and all is well great job guys

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.

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
