I know this isn't what your asking for but I'd really recommend forgetting the 8.8 and get a Detroit True Trac T-lock for the 7.5, it'll be stronger than an 8.8 and cost less.

How can a 7.5 be stronger than an 8.8 by adding only a truetrac?

Re: any 3.37 gears or 8.8 rear for sale

The weekness in rear ends is the differential. How often have you heard of the axles themselves breaking, it happens but not very often.

For more info, do a search for it on 3.8mustang.com.

Re: any 3.37 gears or 8.8 rear for sale

Why do you want to put a locker in your car???? I am sure he wants to take this on the road as a daily driver. A locker is terrible idea for a daily driven car.

And it's the spider gears that break most often. However, it can break the pinion gear and warp the pumpkin too if you have some power. It all depends on what he wants to do w/ the car. I know when I was in the 13s, I needed an 8.8. But I also had an auto with 4.10s, torque converter, shift kit and slicks to put it down to the ground. And I would spray nitrous off the line. Fun times and 1.7-1.8 60' times too

Your spider gears are what break, and your spider gears are still 7.5" (As Monkey has said)

Re: any 3.37 gears or 8.8 rear for sale

Sorry I keep using the wrong terminology, it's an LSD, not a locker. Just puts power to both wheels, but it's the strongest you can buy regardless of whether you believe it's stronger tha the 8.8 or not. Read the thread for arguements on both sides and decide for yourself.

The diff. may just be stronger but the diff. is not the main thing breaking in the 7.5. The spyder gears are usually the first thing to go.

Re: any 3.37 gears or 8.8 rear for sale

It has been proven that the 7.5 can take a good amount of punishment, but if your going to put posi in your 7.5 and your trully worried about strength, an 8.8 will always be stronger.

I think the 8.8 and the 7.5 use the same axles too right? 28 spline?

Re: any 3.37 gears or 8.8 rear for sale

The 7.5 can support atleast 250 maybe more. When you have slicks and try to hook up is when they start to break, i.e. the spider gears strip/explode.

Exactly what I'm saying! That thing is incredible, and at $354 on that site a real deal.

Re: any 3.37 gears or 8.8 rear for sale

I broke a 7.5 with 140rwhp. I just had bolt-ons.

You can say that adding that posi will make it stronger. It will. But an 8.8 with a posi will still hold more abuse than a 7.5. If he's spending $354 for the posi + ~$200 for gears + $200+ for install, then he can buy an 8.8 for $600 with the gears already set that he wants and bolt it on himself. I'll let you figure out which is cheaper

Even though I don't have a mustang anymore, I still know a thing or two about:
nitrous
drivetrain
engine
turbo
suspension

I helped write the HUGE mega thread on gear swaps over at 3.8 since you seem to be using that as a reference

Your still spending close to 600 dollars to beef up a weak rear end.

You can buy a brand new 8.8 for 800 dollars with 3.73 gears in it.

I bought my 8.8 for 275 dollars with 4.10s in it.

I just do not see the point of beefing up a 7.5 rear end when for just a couple hundred more bucks you can get a stout 8.8 that is tried and true.

Re: any 3.37 gears or 8.8 rear for sale

Here is the deal 8.8 and 7.5 use the same 28 spline axles. They do go bad from time to time. Actually the spiders gears are not what go bad first. It is the clutch packs that wear and that causes the spiders to receed away from the other spider gears and the teeth get ground from contacting the tips of the gears. The 7.5 is a pretty beefy diff but the 8.8 is beefier. I have also seen many 8.8's at the track on close to stock GT's break. If you are not the first owner you just dont know how much the diff is abused. The 7.5 TLok is much beefier than the stock open diff. If you can get a good price on a 8.8 go for it. But I would not waste my money on a high dollar 7.5 LSD when the FMS TLoK does the job well.

Re: any 3.37 gears or 8.8 rear for sale

I agree Danger dude. Everyone agrees that both axles are temperamental as far as breaking is concerned. Now, if some people had actually read what the components of the Detroit LSD are (like 232stang obviously did), they would know it doesn't even use spyder gears. Yes, it's and expensive one, but on the site shown above, it's comparatively cheap when compared to the $500 shown elsewhere.

Re: any 3.37 gears or 8.8 rear for sale

stock 99 up v6's and Gts all have 3.27 gears stock, dont upgrade your rear. www.speedconcepts.net used to carry complete rear ends, minus brakes and axles(easy to use off your stock rear end, those parts are interhcangable)

the weak part of the 7.5 is the spider gears in the rear end, then the gears themselves.

No it is not the spider gears that are the problem they are not weak it is worn clutch packs. The clutch pack force all the spider gears to contact evenly. When the clutch packs wear they cause the spider gears to receed and the gears contact at the tip of the gear teeth instead of the side surface area of the gear teeth. Any gear will wear out if they dont contact properly. I know I have recently rebuilt 3 Tloks and they all had the same problem. So lets stop blaming the gears. It is the Clutch packs fault BY GOD
