Banks Diff Cover:
When the first test videos were coming out I was disappointed he didnt include a factory finned cover like the AAM one I bought. He did all his test showing how the factory curved design was better for oil flow around the ring gear and the cooled covers didnt. Basically saying that was the only option. Then when he announced he was making a cover it was clear why he didnt mention it.
I initially thought it was unbiased too until the second video I got suspicious.I guess I was naive and / or not thinking with the Banks videos, I was really enjoying the tech until I realized it was just an infomercial. Very disappointing and made me question all of it.
That's a really good price on the OE style cover, I just priced one a week ago from a friend at a dealer and even with a generous discount it was over $250 just for the bare cover only.
