Default 2005 and 2006 rear diff inerchangeable???

http://forums.corvetteforum.com/show....php?t=1308118

EXACT QUOTES:

“The 2006 Z06 differential has *never* been interchangable with anything, nor has any of the 2006 differentials in general been interchangable to the C5 Corvette. As stated, the 2005 and 2006 standard LS2 differentials are.”

“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.”

Get that folks? The 2005 fits the 2006 and the 2006 fits the 2005…..interchangeable.

Later, ( 1 ½ years) they stated that it was only 3 cars that were special in 2005 that fit the 2006 diffs. I guess the interchangeable 2005 doesn’t fit the 2006.

I'm not sure and would like some input. There is a lot of crappy tech info on the internet you know. Take a look and have some input.

Jez, I can't believe I missed that whole thread and I have been interested in this topic.

I must admit that I have not seen responses like this from DTE in the past. Makes me think that either there is new management or the whole C6 diff fiasco has got them on edge.

It seems that there is no cut and dry model year definitions but I don't know why they just couldn't say that their original statement about the interchangability between '05's and '06's was misleading to say the least.

In either case it seems that the current best approach is putting a C5 diff in it's place. I never thought I'd see the day when a C5 diff was considered an upgrade but the C6 diffs, particularly the '05's are just so fragile'. They must be made in Italy. <-- Christmas Story

This is funny...

No, we're not on the edge at all.... Guy, SpinMonster, ECSTunedLSX or whatever the hell else he wants to name himself this week here online, is just stabbing back for us proving him wrong in another thread like he always tries to do to everyone else he comes in contact with online these days and his ego is bruised. He's retaliating back like a little boy.....

He's very predictable and it's it's quite funny to see his childish reactions to things when his panties are in a bunch for whatever reason. He just wants to resurect an old thread to try start a fight, but it takes two to fight and we have no desire or even give a crap in the least about him, what he says, does, thinks or otherwise; Nor will we provide the information he wants as justification, because frankly, we just don't care what he chooses to believe or not belive, as we'll not lose one wink of sleep over it in any capacity.

Fire away spinmoster, guy, ECSTunedLSX or whatever you wish to call yourself this week, because your antics are always amusing here. We're looking forward to seeing you try to defend your ego and what you *think* you know about differentials...even though you *NEVER* built one for yourself...

Take care, have fun and amuse yourself, because we'll get a kick out you we're sure. We're done and have fun.

Regardless of the banter back and forth between you guys can we agree on a statement regarding the interchangability?

A. They are not interchangable (this is my understanding)
B. They are interchangable
C. There were too many mid year changes to be able to discern simply by model year
D. None of the above

Also, when we talk about '06 and '06 interchangability can we assume the '07 diffs are the same as the '06 diffs as far as whatever statement we agree on?

to all

I'm not aware of history of this 'issue' or the apparent personal conflicts between the players. DTE may well be correct (or not) in their assessment of this thread or the motivations involved but it seems DTE would be better served leaving personal opinions and animosities aside and simply trying to clarify the question(s). Take a higher road.

When I first bought my 05, DTE on this forum said;

1) The 05 had like three diferent rear ends with mid year changes and that they are not interchangable.

2) That the 05 A4 and M6 is not interchangable.

Thats it, thats what they posted on this forum. Now they say the 05 A4 and M6 is interchangable. Also there is only one rear end for 05.

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. I have nothing against DTE I just wish we can get all this straight, if possible.

I'd like to point out that both Spin and DTE are valuable members to the forum and that neither is responsible for documenting the mess that GM has created trying to get it right.

I would think that a lot of vendors that deal in corvette diffs would have some sort of C6 diff matrix put together though or how else would they sell any diff to any C6 owner other than matching up their core.

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...!

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 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.

You proved me wrong???

I think you better go back and check. It was Matt who pointed out my error which was actually his error since they (SDPC) were the source of the info. You can check the thread again for his appology and how Matt is sending a call tag for the improper part they told me to use. Maybe if you kept your mouth shut and worked on getting that 2005 diff to fit a 2006 to prove yourself right then you wouldnt have to admit now you made a mistake.

I think you should step up when you make a mistake like saying 2005 and 2006 diffs are interchangeable and admit it instead of telling how there were 3 cars that existed in 2005 to state interchangeability. There are no 2006's that accept a 2005 (but of course they are "interchangeable between themselves")....but here we are in 2007 and I PROVED YOU WRONG. The thread is there for all to read for themselves.

Couldnt leave it alone. You jumped in there just to start a fight and I'm the little boy. Riiiiiiiiight.

Long winded when all you have to do is answer:

Are the 2005 and 2006 diffs interchangeable between themselves? 2005 to 2006 and 2006 to 2005. YES OR NO. But we will never, ever, ever, ever, ever, ever hear the answer. You will get another reply, many paragraphs, well written, to tel us about their engineering experience, happy customers, products available for all vettes since 1996, but no info on the accuracy of a statement that requires a yes or no.

The 2005 diff does not fit a 2006. And, aside from 3 'special' cars they stated that accept the 2006 diff, the 2005's do not accept a 2006 diff. They are not "interchangeable between themselves". They were wrong then and they are wrong now but will only state that I am an "internet legend in my own mind" and have all the answers so they dont have to answer.

Its 72 and sunny so im heading out on the boat....enjoy the jagged pill.
