Serpentine Belt
Monday, March 17, 2008 11:07 PM
So I have the AEM pully kit on my LD9 and it came with a larger alt pulley. With the kit came a new belt to work with the pulley. I am wondering if anyone knows the length of the OEM serpentine belt size for the LD9 as well as the size of the AEM belt that comes with the kit. I ordered the GM s/c and want to keep the alt pulley but I need to find out the length difference so I can determine what sized belt I need to buy to work with the s/c. If anyone has an idea of the different sizes of the belts or if you are running the s/c with the AEM alt pulley what size belt needs to be used. Anyone with some info would be awsome!

Is the AEM pulley going to clear the supercharger?
