Anyone use one of these serpentine belts? Mopar belts are back ordered at all my dealers and this was what I was able to find at an O’reillys in terms of “premium”.. I guess they put Kevlar in the belt instead of a poly based thread. This makes the belt stiffer and that is what brings better performance when using a supercharger (my jeep is not supercharged). I think I’m gonna order an OEM belt and replace it when it comes in. I’m sure in the right application it would be a nice belt (the RPM) but for our jeeps.. I’m not quite sure
