Good Quality
I received a Dayco Gold Label-Diesel Grade Design belt. The generic sizing is 8PK2415. The belt looks well made and installed without issue, after remembering to slide the skid plate to the side to remove it on a Tundra. The belt threaded on without issue. There is a diagram of the belt routing with the belt packaging though it's easier to pay attention to the original belt routing as you take it off. Some people elsewhere mentioned some belt squeal. I haven't heard a single chirp, even on startup, with no belt dressing used. The belt has been quiet. Would buy again.

Absolute junk
I'm a mechanic. Old belt was fine . Never SQUEAKED. THIS ONE THE COLDER IT GETS THE MORE IT SQUEAKS...bad now. Just on start up for the last million starts. Was hoping it would break in and got worse. Buy the green belts there the best or spend a bit more on OEM.

Exact fit for Tundra 5.7, replace the tensioner also to stop squeals!
After going through 2 other belts that squealed on start up, I replaced the belt with this one and the DAYCO belt tensioner (89378)and now it sounds just like it did when I bought it (Quiet!) and fits just right. It even has the engine diagram to ensure proper routing.

Not OEM but high quality
The idler pulley I took off was imprinted as Dayco. Ironically, the belt was not. My belt was a Gates.

Belt squealed horribly.
Installed as part of the 100K maintenance on my 2013 Tundra. Thought it might be idler and tensioner so bought them also and no change. Put the old belt back on and no issues. So this will sit on the shelf...
