Of course you guys are right. In my opinion a stock 12 bolt High Performace rear with the Hi Impact axles and Series 4 positaction is stronger than the standard bread and butter 9 inch. Factory rear ends the Dana 60 is the strongest and the cheapest as well as heaviest.
I have seen so many guys put regular 9 inch fored rears with factory regular duty carriers and retainers and be disapponited because they had read the 9 inch is strong. The factory 12 bolt is at least as strong as factory run of the mill 9 inch and the Mopar 8 3/4 is worse.
Guys without the finds to buy or to build a really tough 9 inch can install a factory Dana 60. They can also jst make the initial hit a little softer so it does not shock the rear end. For example launching on foot brake is easier on rear end.
I have built Bullet Proof 9 inch rears but it is not cheap. You will never make a 12 bolt to be fully bullet proof.
