As a DIY car enthusiast I can undoubtedly say that the ACDelco tensioner is a game-changer .Based on our own experience, it is reliable, sturdy, and an easy install. Its build quality accurately complements the price point, and it lasts way longer than the typical TENSIONERS out there. One downside is that it might not be compatible with all car models, but that shouldn't discourage anyone from considering it for theirs!
