in my 2005 V6, I spun my tires one day, and i noticed that only one tire spun. how can i use both for a good luanch? LSD? should i get the GT rear end? and if i do,, will it bolt right up ? and what would be the benifits (if any) should i change to a GT rear end?
you could change to a gt rearend, but instead of changing the whole axle assembly, buy a traction lock carrier and get the gears you want, it would be mor cost effective and you wont have to fabricate to get the axle assembly to fit

i hate to say it, but i don't agree.
as far as people i've talked to, as well as people on this forum, it's a lot more efficient, cost and labor wise, to drop the GT's 8.8 rear end in. This comes with the gears, traction lock, and a stronger rear end in general.
just my opinion though. i'm hoping to do the 8.8 real soon, and there's a video on youtube of a shop doing it, real simple.

NO FABRICATION TO SPEAK OF, its a simple bolt on that takes a few hours maximum...
will a gt 8.8 rear end bolt on completely on a 2007 V6 coupe? im planning to have the rear end change also. what are my options? thanks
I am wondering the same thing. And what all comes with the 8.8 rear end? And how much do they usually cost?

Yea stlwagon is correct. The GT rear end will fit a V6 Mustang without any fabrication. I put my rear end on a month ago and bought it from newtakeoff.com. I spoke to jason and it was simple. Just unbolt the 7.5 rear end and just pop in the new 8.8 rear end. It was easy and I ended up doing it myself. I do recommend someone to help cuz the 8.8 is heavy. I def prefer this because I tried to buy gears for my 7.5 rear end and I had a bad install and had to get the parts all over again!!!! I say get the rear end and call it day. Its so sick!!!

I also respectfully disagree with whoever mentioned to get the t-lok and gears, it is more cost effective to get the 8.8 rear end then to go that route AND depending on what you want to do with the car the 8.8 will last you longer and give you a piece of mind that your not about to snap anything.
I kno this is one of those discussions similar to a turbo versus supercharger type argument but in my honest opinion the 7.5 rear end can not handle the amount of torque that a forced induction v6 can throw down. What i mean by this is not that once power is added to your v6 that the rear end will go anyday but i do think that with some time at the track of even some launching you will start to have problems, some people have used nitrous and supercharged their v6 and have had no problems but others have snapped it on just a 75 shot of nitrous. Its one of those things where your better off just going all out all at once instead of buying a t-lok then buying the install kit, then the gears, the install kit for that, etc.
PS after reading over the thread again i just noticed you never mentioned going forced induction but hell if you did plan on it i gave you some compelling information on the 7.5 and 8.8

I put the GT 8.8" axle from newtakeoff.
They have a few different gear ratios - 3:55, 3:73, 3:9something, 4:11
The whole axle is a cheaper and better choice. The 7.5 is just not a HP thing.
I had to take the brake rotors off my 7.5 for the 8.8.
One of the things I liked most about changing the whole axle is painting the replacement. Ford didn't put any kind of finish on either axle, so my 7.5 is covered in rust. My new 8.8" has a nice black paint job.
How much would a decent set of 8.8 and gears be with installation? any rough estimates?

The GT take-off rear ends that they're selling come with 3.31, 3.55, 3.73, 4.10, etc gears as well as Ford traction lock pre-installed. Prices are...
3.31 $600
3.55 $805
3.73 $850
4.10 $950
Now if you dont feel comfortable removing major parts of your car, such as the rear axle, then you'll want someone to install it for you which is going to cost you BARE MINIMUM $100.
So suppose you're looking for a 4.10 gear with Ford trac-lock. You're looking at at least $1,050, probably more installed.
Now lets look at the v6 rear end. It's a 7.5" and there are plenty of N/A and F/I guys running around on it making around 300rwhp without problems. If anything, you'll have to replace the trac-lock before you have to replace the rear end. A set of 4.10's will run you roughly $150-250, $100 for an install kit and another $200 for your trac-lock. Thats $450-550 before installation which usually costs around $300. So when all is said and done, your gear job is going to cost about $800, roughly $300 less than buying a brand new rear end assembly.
Not to mention if you buy the gears and tlock then you get to choose the brand you want.
Any way you look at it its cheaper to install new gears and tlock in your 7.5". The power handling capabilities of the 8.8" should be a moot subject unless you're planning on making well over 300rwhp.
Of course if you install the 8.8" yourself you'll save that install cost but your parts cost is still more than your installed cost for the 7.5". We could sit here and argue about this all day. Some people will stick to the 7.5", myself included, and others will choose the 8.8. Its kind of 'whatever floats your boat' but i'd like to try and dispel the myth that installing a takeoff rear end is cheaper than a gear job.
