I think we saw earlier in the post that the 9" is superior in many ways, and my 3 channel ABS works great on my 9" and was seriously a piece of cake to hook up.

what are the differences in axle sizes between the two?

Happy with my 12 bolt but between the 2 I'd go 9 inch.

9" can be upgraded to 35 spline 1.5" to match the 60. Then again both can be had with gun drilled 40 spline as well....all depends on the $$$ you wanna shell.

It seems that both are very comparable as far as weight, strength, power loss, etc. Only differences are that a 9 inch has removable center section (doesn't matter for most people) and Dana is cheaper (if you are smart, you'll get a new driveshaft with either rearend).

Couple questions though:

1. Which rear end is noisier? That is my major issue with 12 bolts...they are SO loud. I've never heard a quiet one.

2. Would a 9 inch be A LOT easier to work on if it got noisy and needed a little adjustment or new gears or something?

I love the S60 I have in my car, and it was much cheaper than a 9" (who doesn't get a new d/s if they are planning on launching the car hard with some power).

1. my s60 isn't loud, atleast to me I don't really hear it at all.

2. Despite what some people say, how much do you really work on your car all alone and have all the tools? It is easy for those that have done it a few times, or have the time and patience, otherwise a gear change costs like 200-250$ parts/labor (atleast in illinois where I go).

Thanks!

Anyone else want to chime in?

BUT IS THIS APPLYING TO ALL AFTERMARKET 9" REARS? IF SO THEN A MOSER 9 FROM BOB OVER AT EPP IS ON ITS WAY TO ME...

------------------------------------------------------
Cliff's notes:
- Ford 9" pinion is significantly larger than a D60, closer to the size of a D80.
- Ford 9" ring gear is thicker.
- Ford 9" pinion is supported on both sides.
- Ford 9" has greater vertical pinion offset, giving it more teeth in mesh.
- Ford 9" pinion teeth are at a steeper angle, putting more teeth in mesh.
- Ford 9" has thicker teeth.
- Ford 9" is lighter than D60.
- Ford 9" main caps are larger and thicker than D60.

And, all these don't even mention how much easier it is to build and work on a 9".

in one word yes, aftermarket 9"s usually have better stronger components and designs

engineermike

Yes, those are features inherent to the architecture of the 9".

Mike,

Would you consider duplicating your three channel set-up for someone elses 9 inch? I would prefer a 9 inch, but don't want to lose the ABS, and unfortunately, I am not an engineer. I'm sending you a P.M. Thanks!

so do you have to mod anything to fit the d60 under a f-body? tq arm or tunnel? what about that sweet *** cover they sell for it are there any issues with clearance with the phr?

Sean Collins

High speed prolonged driving with a 9inch will build more heat due to the lower pinion placement and more Worm Gear motion of the 9. However how many of you guys cruise at 100+ mph with a 4.10 ratio ? if not the a 9 is as good as any Dana60 except for the fact that when you add in the brackets for the 9 the wieght difference wi thte 60 is about zero or at least was when i swapped from a 9 to a s60 actually lost 2 lbs but that has to do with the TQ arm bracket and other modifications made when the 60 was installed.

hopefully a 3 channel version can be readily available for the 9". till then ill just wait.

im lowered with D60 and the "S" cover on it and the sway bar/ PHR clear fine. My BMR non adj. torque arm did rub on the floorboard a little so I had to put the stock one back on.

the drive shaft should not be a factor, cause if your getting a strong rear you should upgrade the drive shaft also!

99zman

iTrader: (23)

how is the s60 cheaper than the 9, the $200 cheaper base price is nice but the new drive shaft takes up the savings? i am having a real hard time dieciding on wich rear to get, any of them im looking at about 3k instaled. but they all have issues, gear noise, leaking, tq arm mount (moser 12) some say the s60 housing is weak? 9 inch you have to bang the **** out of your floor board. i mean all that money and you still cant get a solid performer? they are all stronger than the 10 bolt but all have issues also.

engineermike

I got mine installed with everything for about $1600. Also, the floor board mod really isn't that bad.

99zman

iTrader: (23)

if i could get one for $1600 id do it, form epp $2500 shipped and the rest labor probally around 28 $2900 but you get the point. so the floor board mod isnt to bad then? someone posted a link to speed inc's site where there were pics but i cant seem to find them.

engineermike

If you are that concerned with cost, then do it yourself and half the price.
