Yes, I have the 4.3 with A/C. It was a little snug when I put it on, but it fit nicely. That belt is silent compared to my old one. I wanted it to be a little snug, because the old one chirped like crazy. And ferret, I'm glad you are happy with your new belt. Hopefully your chirp does go away.

 

Still have a chirp chirp, but not the constant loud chirping squealing noise like before. Was hoping gatorback would fix my noise like everyone else. Just been keeping the radio turned up, and don't go through any drive-thru windows where I can hear the reflection of the noise amplified.....

 

If it is still chirping even with the gatorback, you probably need a new belt tensioner.
