10 bolt, 12 bolt, 9 inch
#22
Many people, stock and some mods, have well over 100,000 hard driven miles on their stock 10-bolts with zero problems.
The discussion has happened many times on here. Also, fyi, mine is a hard driven m6 with 101k miles on it.
The guys that break 10 bolts are the guys that put drag radials or slicks on them with high hp, and launch at high rpm.
Also, running a larger rear will actually cost you performance and power due to the extra power it takes to spin the heavier parts. Think about a fly wheel in a kids toy car. That little light car, think of how hard it is to push it forward relative to the light weight of the toy, because you are spinning up a weight, which takes a lot more energy than just moving the same weight a direction without spinning it also. I hope that made sense to readers.

Also, from what I understand, where the pinion rides on the ring gear, which is why the ford 9" is so much stronger than the ford 8.8", the 8.8 lines up like O--- where the 9" lines up lik O___. probably more to it than that, but just trying to give as much info as possible.

my ten bolt has held up for 100k and works great. on the day it bites it, i will prolly go the 12 bolt route bc i will never own slicks. at least not for this car.

Only 2500 bucks. Wow I was always under the impression it was like twice as much. Also what is about the limit a 12 bolt can hold horse power wise. Like Horse Power+Slicks=? Where will the 12B brake?

Don't believe the hype about the 10bolts being weak.

2500 bucks? lol, I paid half that. I got a moser 9" housing with axles for a thousand bucks, and a center section for 250 that included 4.11 gears and a spool all set up. I spent 1300 bucks. Its not too noisy either, but then I couldnt hear very well over the open headers and the neighbors bitching.

To the OP, do you plan on getting a new rear end, or just intrested in learning about them.
If you plan on buying one...
Everyone missed the biggest question
What kind of power do you want to be making at the rear wheels?
Not true, if he has an auto and plans to be making 1000rwhp w/ sticky tires i would never throw a 12-bolt on the car, thats more of 9" and D60 territory.

What exactly is the difference between having a lower spline count vs a higher spline count??

It was more out of curiosity and wanting to learn the difference between them.. I do plan on getting a new rear end at some point. I just dont know when. As for which one I would pick, I think I would just go with the 9". I am wanting around 400rwhp so I think that would do me fine...

You say 400rwhp but that will get old after a while and you will want more.
Goodluck.
