From the Chevy press site: https://media.chevrolet.com/media/us...2019.tab1.html
G96 ELSD (ZL1 non 1LE)
3.73 (manual)
2.85 (automatic)

G80 ZL1 vert and SS
3.73 (manual)
2.77 (automatic)

Saw a GM Authority publication that ZL1-1LE ratio was 3.93 on the manual ... but I couldn't confirm that on the Chevy press release site.

I also read somewhere (probably on these forums) that the ring gears are welded in the G96, and possibly also G80 but not sure. So the only way to upgrade may be to build/buy a completely new rear end.
