I got this rear diff for a project but decided to not use it since the other parts wouldn’t work. It is from a B7 RS4 and in great shape. Would be a fantastic candidate for a limited slip install and you wouldn’t be required to have downtime for the car while in the process of getting the limited slip installed into the case.
SOLD!
