Who build ford 9inch for the 03 mustangs? I found that currie has the housing for 590.00 i figured about 1100.00 to do a 9 inch and it will prolly be just as high to build the 8.8... any info

 

[crazystang25]

I have a moser 9 in' in my car.

 

[crazystang25]

And it will cost more than $1100 to build the 9 in". And Im sure it will cost more than $1100 to build the 8.8 as well. What happened with yours?

Ive been running the stock rear end nothing. Im hitting the strip up next year so i need a rear end under it!! i figured if i went with the 8.8 im going with a eaton 31 spline axles but then i would need to do some bracing to the rear and as well. but i think i added up one day it was under 1100.00 to build my current 8.8... so if i was to buy the bracing needed for the 8.8 id say i would have around 2000.00 in my 8.8 . You got any pics of the moser unit u installed?

 

[Driver]

What bracing? Put a good diff in it and 31 spline axles and let it eat. Upper and lower control arms should be plenty. I've cut plenty 1.5 60s on 17" radials on that setup with 700+ rwhp.

Ill see if I can find any on my compy since my phone constantly effs up.

well i know a lot of people will buy CHE stuff to brace the tubes on the 8.8 but i might just weld up something to stiff up the tubes and weld the tubes as well. Ive got all the rear end stuff on the car already MM panhard ,mm LCA, BMR uppers. I know i can get the strange 31 spline alloy axles and c clip elim for a little under 500 and i would prolly put a eaton diff in it. But some say even a built 8.8 wont last and then there is that ive heard that when you put c clip elims on 8.8 they will leak. so im doing a little search both ways im pretty sure if i go 9 inch i will never need another rear end!

 

[crazystang25]

no you wont need another if you go the 9" route. I just went ahead and did the detroit locker with 35 splines in mine!

 

[crazystang25]

Ok, remind me in a couple days via pm since I am having issues for some reason on uploading photo's.

If you do a 9 inch, be very careful which housing you choose. You actually have to cut into the housing for the upper control arm mounts to maintain correct suspension geometry. I have installed a moser M9 housing into a 2001 Cobra, and although it was a nice piece it did not have the correct suspension geometry. This is especially true on the housings that have the large fabricated centers.

thats info i did not know thanks for the heads up!

I have a Strange Engineering 9" in my car. Strange Engineering

The Strange housing has the notches for the upper ears. Here's my setup. You can see where the mounting ears for the UPR upper control arms are notched into the housing.

Ok these are about the best pics I have of mine atm. I took these after I dropped it and painted it while I was putting my new exhaust on! But I like it a lot.

 

[crazystang25]

It does give a really good shot of the new exhaust though!

the 9 inch rear is the last rear you should have to buy.Things to think about most if not all 9inch rears offer no ABS it also takes more power to turn a 9inch .When building a 9inch rear double what you think it should cost .

 

[ultraspeed]

sharad and crazy stang did u half to do any modifying to get the uppers to work? or was it good to go? also if u do not care of me asking how much was the moser and the strange setups with the gears the whole nine yards?

 

[crazystang25]

my whole setup with 3.70's, detroit locker, and 35 splines was around $2500-$2700. cant remember exactly. As far as the uppers are concerned I had mine installed before I knew how to do drivetrain setups and they had make the mounting brackets for the install.

 

[crazystang25]

And as far as a power loss to the wheels from the 9" I think its minimal because I can still spin street tires half way through second gear with no problem.

 

[Mod Motor Maniac]

You can get ABS to work in a 9 inch with the right axles and such. The absolute best part of a 9inch is the ability to have another pumpkin set up so that you can swap gears in less than an hour. This is great for dual purpose vehicles, or even a car that will see open track and dragstrip duty. One of my cars has a 9inch and I have 3 pumpkins with 3 different gears, it's very convenient.

My Strange 9" was a direct bolt-in with the UPR suspension, but keep in mind that we make upper control arms and spherical bearings that are specific to either the 8.8" or the 9".

Since I saw your other thread talking about X275, I'll assume that you'll need a setup like my 40-spline rear. It runs about $3k. Strange Engineering

And as far as a power loss to the wheels from the 9" I think its minimal because I can still spin street tires half way through second gear with no problem.

I think that's an old generalization. The 9" in my car does not even remotely resemble an OEM 9". I know its bearings are nothing like the OEM bearings. It seems to spin fairly freely, however, I would have chosen this rear even if it used a few more hp. By the time you brace & reinforce an 8.8 enough to live in an application like mine, you have as much money and more work in it that you would have in a Strange 9. I watched Chris Tuten run 7.20 @ 200+ on an 8.8... but it was also leaking oil at the center section. No bueno.
