When the article mentions the "massively heavy nine inch dana" the article loses some credibility, and the bias (from a company that builds nines, almost exclusively) is readily apparent!
They also conveniently forgot to mention that those strong nines are LOADED with aftermarket parts.
A Grey iron center, weakass Ford posi, 28 spline axles stock nine inch isn't even in the same area code as a stock Dana 60, strength wise.
