Fel-ProBS 40640 Rear Main Seal Set

Quality parts as always from Felpro! If removing the rear seal housing, there is a special tool needed to center the cover on the crankshaft! Failure to do so can and most likely will lead to premature leakage

working just fine . No great deal on the price .

So i purchased this to repair the rear main seal. Originally i received the kit that has this copper/aluminum gasket with black silicone on it as pictured in the photos. I had to return that kit because the seal was damaged. I was sent another bs40640 kit also branded fel-pro. This one however was a steel gasket with blue silicone.Frustrated because i didnt know if these parts were original i went to the dealer to buy it. They wanted $80 for the gasket only and it looked EXACTLY the same as the copper/aluminum with black silicone. I then passed by autozone to look at the same kit and they had the blue silicone one one.The round seal on both kits appeared exactly the same.It seems two companies are making these gaskets for felpro so theyre both "authentic". I would have preferred the aluminum/copper colored one as the original one that came out of the vehicle was also aluminum. The steel one had a slightly poorer fit. I ended up installing the blue one and initially there is no leaks. Ill update on longetivity as im only about two weeks into install.

Perfect fit, fast shipping

Fixed my oil leak on a 2007 Tahoe with the 4.8L. Fits perfect.
