Relative axle strength questions

[Stinky]

I've got a '90 3/4 ton 4x4 Sub and I want to change axle ratios. I have 3.45 and want to go to 3.73. I've decided that it will be easier/cheaper to just find a complete axle and change it out.

Is there any real strength dif between a 10 bolt and a Dana 44? Does it matter on a stock rig (235/86-16s for tires).

Same question, but this time it is on a 1/2 ton Sub and I want to go to 4.11. Is a 12 bolt any better than a 10 bolt?

I would argue that the strength difference between the two sets of axles is negliglible. On a strock truck, I'd run either without a second thought.

Agree with Russ, 10bolts and 44's, no real difference same for a 10 bolt and a 12 bolt especially with small tires.

Agreed. As long as you're dealing with 1/2 ton hardware 10B/12B/D44, you can't really go wrong with any of the three, differences are minor.

Yup, tire size is the game changer.

10 bolt rears will explode in a field under 3/4 throttle

10 bolt rears will explode in a field under 3/4 throttle after countless donuts, spinning 33" tires, behind a torquey 400 sbc.

You may have left out some info, Adam, so I filled in the blanks.

You forgot the most important detail....

Adam, as fun as it is to get young girls drunk this photo is a bit incriminating. I mean, I'm still fairly certain she is a minor even though you have disguised her with the 30 rack box.

I'd still do a 6 lug 9.5in 14bolt on something heavy out back though. Especially if you want a govlock. As far as the front a Dana 44 is better only if you want to upgrade. It has more aftermarket support and a wider gear selection.
