Someone please explain 1 - 3 rib diff?
I know this is a newbie question but I did a search and I couldn't come up with what I was looking for... First of all, what is a "rib", and what's the difference between 1 and 3 rib? I'm thinkin about going to a 3.42 gear...

As seen on the picture below, there are 3 "ribs" toward the front of the diff where it mates to the transmission. The 1 "rib" diff only has one toward the front. When using trans/diff brace, there really isn't that much difference in strengh IMHO.

If useing the trans/diff brace, how strong are these rear ends? If it's the same as the truck world I came from, then the taller the gear (i.e., 2.73 vs 3.42) the more strength it will hold? Then i'll prob just stick with the 2.73's and get the trans/diff brace. I'm wanting to go mid-low 11's

That rear did have 300M shafts but the C6 Z06 shafts will stand up to almost anything. Bret's 930 RWHP 02 Z06 runs a stock C6 Z06 diff with stock internals without any issues. He also traps high 140 MPH.
