Now we have tried to come on here and provide unique information that was requested about these differentials, but everytime we state something that hasn't been read on this damn internet that everyone thinks is the Bible of correct information, than it cannot possibly be true; therefore, we're bashed for the info we provide time-and-time again, just because it isn't main stream reading, even though it's accurate. Well, you know what, that's fine then....we're not stating anything anymore...
I don't think anyone is expecting proprietary information. People asking about basics like interchangeability between the years are not asking for such information. I do recognize and understand what your saying but to be frank I have seen you type this same thing for years and it has become irritating. Joining a thread and saying "I know the answer but I'm not telling" gets annoying after a while. I have seen you do this a number of times. I have never seen you actually answer a question. Better if you don't post at all because your adding nothing and at least IMO, hurting your own reputation.

We do have a differential fitment/application matrix already sorted out for *all* the differential models currently in production since late 1996 (including some that aren't) and that is how we currently have global sales of our differential/driveline products to most HP tuners/warehouses all across the USA and over seas. We *never* have problems with gettng our customers the right differential model they need, because we know what questions to ask based on experience.
Additionally, we have engineering information here about the entire Corvette driveline from the manufacturer that the public doesn't even know about, nor will they ever hear it from us, as that's one of our competitive advantages in this market. Are we obligated to disclose that proprietary information just because some internet expert "wants to see proof" for them to believe it??? Absolutely not...! Do we "owe" it to these folks to devulge our engineering knowledge of what we do here that makes us our living???? Absolutely not again...!

Well, you know what, that's fine then....we're not stating anything anymore and we'll just let the "internet experts" who know all, but have never even built a Corvette IRS differential for themselves, give you the answers. That's what their best at.....
We know we build a good product and we know what we're doing, otherwise we would not have the success we have to date for the last 5 years. We're the *only* differential builder/tuner that has invested heavily in the development of premium aftermarket billet driveline components, metallurgical processes and unique differential applications that have ran 8's-9's-10's at the drag strip, successfully competed at the Bonneville Salt Flats and have been supplied to the major Corvette Tuners/Buiilders all across this great country. Our products are even standard eauipment on a couple of high profile cars you'll see on TV soon....
Do I give one damn if some "internet expert" comes on here to tell me that we don't know what we're talking about when they've never even built a differential for themself??? Absolutely, positivaly not- nor do I have anything to prove to them either.
There are three things that are gauranteed in life: Death, taxes and criticism. I can deal with the first two, but I have no time for the last and I can choose to ignore it... There are those that like to set back and criticize those who are already doing it, when they have not done it for themselves. I could care-less what one chooses to believe or not believe based on their limited knowledge from "reading" the garbage information that's mostly promenent on the internet...
The bottom line.....we know what we're doing and that knowledge has led us to our high level of success in doing what we do to date.

I cant understand why DTE wont just answer a couple of simple questions to clarify their own earlier statements instead of skirting the issue over and over in multiple threads. Like NO the 05 and 06 and up diffs do not interchange like we originally thought early in the C6 production. And Yes all 05 Rear diffs do interchange between themselves no matter what tranny the C6 came with, that year only, to the best of our knowledge. Whats so friggin hard about that?
Iam not taking any sides between Spin and DTE, their argument aside would still love to see these answers for the questions above.

Tomorrow Iam going to install a 05 M6 3:42 rear end in place of my 05 2:73 rear end. Then I will know for sure that this at least is true. There is another guy on the forum that did this swap and the rears were interchangable. The latest post I read from DTE now said that the 05 rear diffs are all the same and will interchange between themselves. I hope this is true because I spent alot of cash on this M6 3:42 diff
I will find out for sure tomorrow morning when I pull my car apart in my garage.

Among the 2005 models, I would think internally (meaning inside the diff, ring and pinion etc.) that an automatic with 3.15s would be interchangable with the manual's 3.42 but not necessarily with the 2.73s.

I sure appreciate the vendors who are willing to give short concise answers to questions, who come back to clarify when there's confusion, who skillfully sidestep heated exchanges, and who are secure enough to say "oops" once in a while.
Makes me eager to do business with them.
If they're good at what they do, that's an added bonus!

Well, I'm out. I tried to inject some reasoning here but this is dumb. Maybe I'll check back if/when I blow up my '05 diff, but I'll probably just call Cartek for a C5 diff swap. I used to have a lot of respect for DTE and all the advances they made towards the C5 diffs. Too bad they won't be showing up here anymore. because thats what they said right? We'll miss you DTE.

Here you go. An 05 will not fit an 06-07 or vice versa. The ZO6 is also its own animal. I am trying to get gears built for the ZO6 diff right now that will have two different splines so that I can use the ZO6 diff in a LS2 06-07 but it is a long ways off. As of now if you have a 06/07 you have to use the 06-07 diffs.

Chapter III "When Egos Collide!" I've had a couple of good laughs at this thread. Because misery loves company. I am the first to admit, when i make a mistake i do everything in my power to play the blame game and side step land mines. But when all else fails the truth hurts. So it would be nice if we all stepped back and swallowed a cup of pride. Everyone reading this post has made mistakes and all of us are entitled to an OOPS. DTE we need your expertise and look to you as the experts, which makes what you say gospel. Which is even harder to swallow. So don't make mistakes!

I'm sure there are several tuners here that are "regulars" who could give us the correct answers....but it looks like they're all keeping their heads down and avoiding eye contact!

I think some of the problem with the interchange question is in the teminology. Some are saying differential interchange when they appear to mean ring and pinion interchange.
Back two years ago when the '05 was the only choice all the posts seemed to agree that the 2.73 housing would not accept the 3.15 or higher gears so there were at least two housings for '05; The A4/2.73 housing and the A4/Mn6 housing that accepted the 3.15 and higher gears.
Then the '06 changed the frame mounting points of the housing (but kept the same gears?)? Will the A6 housing accept higher gears or is it like the '05 where the housing has to change also?
The '06 Z06 used the '06 housing and gears BUT used a different transmission output shaft and diff input shaft so the Z06 diff. required the Z06 trans?

Nah, nah, nah, nah, they said:
“The 2005 and 2006 C6 differentials are in fact interchangable between themselves, with the 2006 model's case being a bit stonger than the 2005 unit due to some addtional external webbing present, amoung other minor improvements.”
They didnt say internal parts ring and pinion, they said the differential specifying the stronger 2006 case.

Cartek's R&D car is a 2005 no less (the weakest year for rears of all) and it ran in the 9's at the track. They posted all this info about the differences between the 2005 and 2006 diffs long before "the experts" posted months later to state an obvious false statement. Here is the original post from Julio himself:
http://forums.corvetteforum.com/show....php?t=1201399
When I saw the mounting pattern in that thread I knew it wouldnt fit a 2005. Here are the pictures of the 2005 and 2006 diffs: do they look the same on the mounting pattern? No but no one would ever say they dont interchage meaning 2005 to 2006 and 2006 to 2005.
You have to be kidding......THE experts. Save yourself 300-400 bucks and go to an in house builder to get gears. Cartek charges 1700 installed, not 1700 plus shipping for the diff and you then have to ship a core back (and pay for shipping) then have to find an installer and pay labor charges totaling over 2000 for a gear swap.
And who pays the labor charges if a diff intalled isnt good? Where does the car sit while you ship the diff back and wait for a replacement?

I dont know anything about differentials, but the comment on Spin's IP address and conversations with himself is not true....I dont think we want to argue the particulars of WAN IP addressing, Network Address translation, and provider spoofing...
Can ANYONE give us a YES or NO on the topic? Seems like a simple enough request....

By the way, ECS does do in house gears too and for only 1600 installed w/HD shaft as per their advertising here on the forum.
