2015 GMC Sierra 5.3l
Exact OEM replacement. Replaced all 3 belts on my 2015 GMC Sierra 5.3l along with a new tensioner. Is a new tensioner necessary? Probably not at ~87kmi but it’s one of those things where while you’re already in there, and it’s easy and cheap to do, just do it.

Good GM Part Good Price
Good GM Part, great price discounted for packaging damage, went on easy, quieted front of motor down with this and new serpentine. Went on my 2015 Silverado 1500 5.3 all stock with 130K miles on the original parts. All good 👍👍!
