These are NEW old stock gears that have been discontinued from US Gear. This is a STREET gear this fits the 8.875 Diameter GM 12 Bolt Car Rear End and is a 4.56X Ratio. This is a Thick Gear so it will need to be a 3-Series carrier to fit. We have a pallet of these and they are new and unused. The boxes may have some dust but they have never been installed or ran at all. If you are interested in buying several at a time we can make a deal!
