Hell, I think I'll sell my S-60 and buy one of those cheap 9" rears. Apparently they've came down in price a bunch since I bought my S-60. I have now learned that Dana's are junk unless you run Prius power . Apparently the longer these posts go the stronger the 9" gets, I'm surprised that dump trucks and semi's aren't using. Just look at all the money they could save over those monster Eaton's.

Why don't we have a sticky for this, it could be a one liner. Dana's are weak heavy junk, buy a cheap 9", it'll live forever.






Unbelievable. I better scrap the Dana out of my Duster too. I'm not an expert on the subject but I don't really think you could go wrong with either in 90% of the applications we use them in. I will say the one in my Daytona is a well built 9" with a strange carrier and I shattered a set of 4.30 gears at Norwalk and it is a pretty light car (2400 pounds) and was only running 8.60's at the time.
