12 bolt

Having a ford part on my truck is my biggest issue just looking to have it more original. Just curious what make the ford 9inch stronger then 12 bolt?

The pinion bearings are larger.
There are 2 pinion bearings on the shaft, and one on the nose.
The pinion offset is greater resulting in more surface are contact on the face of the ring gear.
The axles are positive retention style at the hubs, no c-clips.
The housings are arguably stronger(depends upon the style/year)
The center section can be dropped out in about 25-30 minutes to make gear swaps MUCH easier.
You can set up new gears on the bench.
You don't need case breaks on the diff carrier for deeper gears.


I am sure there are more good reasons, but those are among the most common.
