Default C5 vs. C6 rear differential

Hey,

I know they're stronger, but does anyone know how much difference in strength there is between a C5 and C6 rear end and then how much more is gained with the C6Z06?
I am in the pursuit of approx. 750rwhp and am trying to figure out what to do with the rear end.

rumor is the '06 diff. is stronger than the '05. however there are numerous '05's with 700+ hp/trq that have survived.

ps. don't forget the half-shafts.

The '05 C6 diff had a single rib diff and the '06 and on have a 3 rib design.

I was told by TJ at RPM transmissions that my 02 Z06 Diff was a 3 rib as well and therefore didn't need a DTE brace. Just a diff upgrade, shaft upgrade and don't launch hard without a trans output shaft upgrade.

Like so many others before you, you were given grossly inaccurate and incorrect information regarding what application our differential strut is used for and why... I will set the record strright for you by providing you with 100% accurate information from the designing engineer who created the successful track-proven product 5 years ago- me.

It does not matter if your car is equipped with a 1-rib differential case, a 3-rib differential case or a million-rib differential case for the likelihood of transmission/differential case fracture to occur in that area due to metallurgical fatigue, deflection stress or excessive shock load events.

In all of these instances, there is still only 5 meager fasteners between the transmission-to-differential juncture where the greatest probability of fracture/breakage will occur. You can have any amount of differential case webbing count you want under the car, but the weak mounting point at the transmission extension housing still remains and is at risk, due to the light duty cast aluminum parts in that area.

In other words...a 1-rib case will fracture just as easily as a 3-rib unit would without the use of our product, because the small connection point at the transmission still has not changed and it's still weak- even though the differential case may be stronger by itself.

Our product protect both areas from fracture, regardless of differential case design and it's proven itself successful time-and-time again in numerous high powered drag cars over the years with varying powertrain combinations. Do a search and you'll find most successful high powered cars are using it to this very day with success as well- including our newest success of our driveline products being in Paul Smith's 427ci. powered C5 Corvette that just won Pinks All Out in Atlanta, cutting 1.3's 60 ft. times all day long with the wheels in the air!

It matters not to me whether you use one or not- it's your car and your wallet, but at least you can make an educated decision on which way you need to go when you're equipped with *ACCURATE** information to make the decison with. Good luck!


Regards,
Phil

Hi Phil, can the DTE brace be installed without removing the diff from the car? Also, any word on the cast iron diff you guys were working on a while back?

This same statement was made in the C5 section, have you found those pics of the broken 3-rib cases yet? We are all waiting patiently.

thanks

I broke my differential case, twisted the DTE brace, but did not break the transmission in my 2006. This proves DTE's statement about the brace. I'll order another brace after I decide to go with an automatic or stay with the 6 speed.

Do you have any pictures of the carnage? Sounds like you have a lot of power, or were driving pretty hard.

Hey Tom,
Just sent you an email. I still have all the carnage here somewhere. We sell a new brace for the C5's from Pfadt I think that will eliminate the diff wanting to twist in the C5 and causing a fracture, they did a very good job on it. As far as the C6, it is a better design then the C5 was, but Tom must have hit it just right because it basically spit the pinion right out the back of the 06-08 housing which is pretty beefy. This is the only 06 up diff I have seen that has blown up this way. Blue, if I were you, I would install a ZO6 trans and diff and then you won't have to worry about it anymore.
