What the title said, I've heard this twice now and wondering if it was true and what the difference was between them.

The only thing i heard about 05-06 is the differential and driveshaft are a little tougher cause the flange and drive shaft are a little bit bigger.

For 05/06 they did revamp the halfshafts.
The axles for the ls2's are a little beefier than the ls1's

The 04 outer shaft dia is right around 1.1" and the 05-06 dia is 1.25"
The 05-06 half shafts will interchange with the 04's, they have the same bolt pattern and are the same length. They bolt right in.
Yeah, the 05/06 are a little beefier.
