Dana 44 Vs. Ford 8.8 Vs. Chevy 12 bolt

How do they compare in strength?

They that can give up essential
liberty to obtain a little temporary
safety deserve neither liberty nor safety.

Re: Dana 44 Vs. Ford 8.8 Vs. Chevy 12 bolt

The 8.8 is considerably stronger than D44. There was a series of break tests in one of the off road rags, a couple of years ago. The D44 snapped at something like 4200 psi, the 8.8 went past the machines twisting power at like 6200 psi, without letting go.
I beat the piss out my 8.8 with over 300 ft/lbs of troque at the rear wheels and 130:1 gear ratio. I recently snapped both axle shafts (they were stock shafts), but I was running in idiot mode when I did it. I never broke a set of my Mosers, and I running Superiors now.
There are very few down sides to the disc brake version of the 8.8, up through probably 38" tires.
Im not sure how, well the 12 bolt holds up under heavy abuse, I dont see too many of them, being used for hard core wheeling.

Yep, the original article on the 8.8 (in a YJ) was the 7/99 issue of Fourwheeler.

Supposedly Warn was the actual tester, and yes the machine maxed out the 8.8 (stock shafts) at 6500 psi.

There was a second article (8.8 in an XJ)in 4WOR (I think) that had testing that revealed a more modest strength gap between the 8.8 and 44.

Actually, since I've been researching the 8.8 (2 years now), Jeff's is the only actual shaft breakage I've heard of, but then again he just broke a 435!

And I've also never heard much about the strength of the 12 bolt.

I think the 12 bolt is the strongest out of the 3. My friends has a bracket car that he had a couple of years that has a 12 bolt in it and it held up to 850hp. he even shocked the hell out it with nitrous, it held up for awhile till he did brake an axle now he put moser axles in it never had a problem. Now he's gotten faster and more hp.
