I vaguely remember reading about the stretch belts when I had my supercharged stick Silverado. The blower and the manual transmission shifts were super violent and it would shoot belts off. Went 8 rib and an innovators west kit for the serpentine belt but then the AC belts started flying off. No idea what I did to fix, I almost wonder if I went to a stretch belt too.
I was kinda worried as well, with this second order I’ll have a dozen of so pieces left as spares. If they totally suck and just all go out I guess I’m out $230 but I’ve wasted more on less. I do sort of wish they were RGB color changers, the white is almost too much, a softer 4500-5000k would be nice. These are 6500
