Default What is the gear ratio of the performance Axle in a 1994 Corvette?

Hi, I know 2.59's are stock on a 1994 automatic. What would it be with the performance ratio? Thanks

There is a rumour that they were 3:07's ??? Don't hold me to that but it sounds right. Go in under search and look up some old topics, you'll find it there. :cheers:

So if my RPO list shows GU2 (2.73) and G92 (Performance Rear) - what do I actually have. Is it 2.73 or 3.07 ???

How can I find out what option I had, is it in the VIN somewhere b/c I don't have any of my books or records or anything like that. Or is it stamped on the rear end or something?

I may be wrong but maybe a Dana 44 with 2.73 gears?

Springer,
Try to get ahold of Scorp on this, he can usually be found in the NE section. I bet he know's the answer on this gear ratio situation.

You are confusing yourself. The G** (in your case G44) is the axle ratio that you have. If you didn't have G92 you most likely would have 2.59 or GM1.

You have 2.73's. If you didn't have G92 option, you most likely would have had 2.59.

This case here is why you can't say that someone has 3.07 because the have G92, (Most of the time it is true but there are some exceptions)

So is it possible to have G44 (3.07) without the G92?

Yes, but not likely on the later C4's. 84's came with G44 across the board, the G92 ratio was 3.31. The early C4's sometimes lumped G44 with the auto/Z51 package (85/86 I think) The 4+3 also came with G44.

The hint is AUTOMATIC ... :rolleyes: :rolleyes: :rolleyes: :jester

A '94 with the "performance ratio axle" should be 3.07's. Oh, and all '94's with auto's had a Dana 36. Manuals had a Dana 44 with 3.45
