Still have not gotten a straight answer for the dealership. So I have been talking to DTE about getting one of there Rearends. maybee a stage 2? any body have exp. with there rearends?
Also does any one know if there is a better outpt shaft for the trans. then just getting a stock shaft? Thanks

My tuner HIGHLY recommends them. They have installed many of them in various cars, including the C6.
I'm looking for the recipe to keep this from happening, not how to fix it once it happens...

IMHO whats going on with the diff/trans breaking is "axle wrap". In a leaf spring car you would add traction or slapper-bars to keep the pinion, front of axle housing, from pointing upwards. But in a c5-c6 the engine,torque tube, trans, diff are 'one piece'.
Mounting points in the front of the engine and two at the rear of the diff creating a long bridge. When traction is good and torque applied its trying to force the middle upwards. Thats why most of the damage is on top off the trans/diff cases. A stronger trans output shaft might not cure the problem. A DTE trans diff brace will help but then the energy will be put on the torque tube.

We ought to all start a club! All who have blown up their diffs can join. But you MUST blow it up to become a member 
All 05's have notoriously weak rear end casings. The gears are strong, but the case is not. That is why they reinforced the 06 and up crowd.

And that said, would the DTE brace, which supports the top of the diff case, provide good protection against this kind of breakage?
Has anyone seen a DTE equipped C6 rear break?
Oh and for those planning to put a 06 rear in their 05, here's a thread showing the differences and outlining the reasons why it's not an easy change.

[QUOTE=Joe_G;1558405750]You raise an interesting point. I'm certainly not an engineer, but since our pinion gear is at the back of the ring gear, wouldn't the pinion try to climb down the ring gear (instead of up the ring gear like a normal diff), causing the front of the diff try to torque down (against the new side cover mounts), and the back to torque up (against nothing, compared to the C5 mount under the back of the diff)?
No, you are right about the pinion in back but the ring gear is on the opposite side as well. We have c-5 drivetrain sitting on a c-6 rear craddle. At the start of our race the initial launch broke the cases but the car managed to make turn one under full power before the output shaft on the trans broke. Now we run the DTE brace.

I run the DTE brace too, had it on my C5 also. I figure it's so cheap it's silly to not get one if you change your gears and have the diff out anyway. I haven't seen a posting of a C6 rear broken WITH the DTE brace, so that's good.
What kind of times are you posting on the C6 rear?

I have not heard anything yet from the dealler I will ask them tomorrow . They said they were having a hard time finding a complete rearend for warranty????? But I did find out that Bowlers performance trans. says they have a better output shaft if any one else is looking. http://www.bowlertransmissions.com/
