C7 CV Axle length?
I was looking at the c7 cv axles as they seem to be really strong. They're thicker than both the c5 and c6 axles for the middle shaft. But have the desirable 33 spline stub, and appear to have a 6 bearing inner CV. The c5 does use a 6 bearing inner CV and the c6 has that 3 ring bearing design that breaks easiest.
Does anyone know what the c7 axle length is? Or what "compressed" length means? I see that they're listed as 24.7 ish inches.
The c5 axles don't work in a c7 due to the outer stub spline count being 31 rather than 33. But I also don't know if it has the same spline size as the c5/c6 diff output shaft.
Any info on this would be awesome. Could be a wicked upgrade, even over the c5 shafts.
And has anyone broken c7 stock axles? What kind of 60'

I guess I found my answer:
The c6 "overall compressed" cv length (at least of a "rebuilt" aftermarket cv axle) is 28.82".
The c7 cv length is just "compressed" at 24.787".
I doubt they would be two different measurements, but it is possible.
Both seem to have a 41 spline inboard stub spline.
Also I think the image for the c7 not having the weaker inner cv bearing design might be just a stupid stock photo and not actually the 6 bearing design.

Also I'm assuming that axle broke on a car with differential bracing? As in it didn't have wheel hop?
The CV joint is weaker on the c6's. That's sort of the root issue. But I believe that you might be able to swap the shaft to the inner cv relatively easily. Depending on the retention mechanism of the shaft. The c6 (33 spline) uses just a snap ring to retain the three prong that hold the roller bearings.

Sorry long ago trashed
No differential bracing. It actually broke on a 1-2 shift. Car 60'd about a 1.48 on average on this setup.
My car had a cam and 3600 converter here. I've had customers with stock converters break them as well.
We will get you right my friend
