Details:

I bought this new and did not use it. This unit is the 6.98 /4.75 version, so it meant to under-drive accessory belt. Absolutely no damage or issues. This is a new Vortech 8-Rib lower crankshaft pulley for supercharged applications on Ford vehicles from approximately 1985 -1993.

This particular listing is for only the pulley itself, as shown in photos. It does not fit 1994 /1995 Mustangs or Cobra.
