I totally recommend the Goodyear "Gatorback belt". I drive an 2001 Tahoe 5.3l, had the squeaky serpentine belt, It was still a good shape belt, but the squeaks were more of a nuisance. So I decided to give the Gatorback Belt a try, and overall I love it. No squeaks, squeals, or any kind of noise. Its very quiet. Autoplicity made it easy for me to check and make sure this belt fit my year and model vehicle. I didn't have to contact customer service for anything, so far (haha).
