While sorting items in the parts room, I ran across this belt. I removed it from a running parts car several years ago and upon closer inspection, it turns out to be an original supercharger belt. Note the KF part number debossed on the belt.
As an FYI, if you're looking for a replacement supercharger belt, Dayco makes one that actually fits Peterbilt trucks. It's part number 28580...several are on eBay. The older stock Gates number is 688.
