Review on Fel Pro 2302 Rear Axle Differential by Collin Donahue

This is the best gasket for 9" Ford. With a thin steel insert it is much easier to remove than just a paper gasket. You never think you'll delete it, but I did 3 last year. I wish they all had this block. I also use a super thin layer of Permatex Ultra Black silicone on both sides.
