Ring and Pinion question.
I bought a set of new Motive Gear 3.90.1 for my C5, I was under the impression that the ring was 39 teeth and the pinion is 10 teeth, The gears I got are 11 teeth pinion and 43 ring, Anyone have input on my delema? I e-mailed Motive Gear, But I guess they are gone for the weekend.
Thanks in advance.

3.9 X 11 = 42.9. Close enough to call it 3.90.1

What has me puzzled is Motive says their 3.90 gears are 10 and 39, Not 11 and 43, The kit I got is the V855390L.

If you do a lot of highway driving, 70mph+, you will most likely not like a 3.90 gear. But will be a lot of fun city driving!
I have a 3.42 and the rpms at 75-80mph are around 2400. Would not want them any higher!

I don't do a lot of highway driving and when I do it is around 70 give or take, I feel I should be fine, I am getting them installed next week I hope.

Must be a misprint in the liturature.
Did you count the teef?
As was stated, a pinion wif 11 teef is more strongerer than a pinion wif 10 teef.
Now it's time to go brush my front toof for the week.......
So what is the cost for this work? Are you taking them a diff or the whole car?

All C5/C6 Corvette ring gears have 41 teeth.... except a 3.90 which have 43 as mentioned above.
16-41 = 2.56
15-41 = 2.73
14-41 = 2.93 (cadillac XLR)
13-41 = 3.15
12-41 = 3.42
11-41 = 3.73 (Motive)
11-43 = 3.90 (Motive)
10-41 = 4.10 (Motive)

You'll do just about anything to catch my truck, won't you?
May have to put my 4:10's back in now.
You should have a quick street ride for sure now.
