What's the difference between the 8.8, 2.5, 3.55, 3.73, 3.9, 4.10, and 4.3 gear wise. I was looking and there were so many to choose from and i didn't know what the numbers meant... anyone help me out?

thanks, but after reading most of the posts, i still don't know what came stock with an automatic 98 v6. and if i wanted to increase acceleration... what should i get.
Would these gears be good for a 98 v6? if from what i've heard it right, i have a 7.5" rear end and 4.10's would increase acceleration considerably. true???
You can look on the tag on your diff to see what came in it. Even post the numbers and someone can decipher it for you. As far as increased acceleration, yeah 4.10's are better, but you'll have a lower top speed and eat gas even worse. Best bet is to see what you have and decide from there.

Gas mileage decrease with 4.10s is overblown. I have them on my 5spd Mach 1 and so does my wife on her auto V6 and we have not noticed a significant decrease in mileage, even on long trips.
You're right. It may not be alot different, but it depends on A) that transmission, and B) how you drive. If you have a 5 spd you'll just be riding the next gear sooner and you'll use 5th more on the freeway. If you like to go 50 in second and dont want to be in fourth, you'll use more gas with the lower gear. lol

I dont agree. I have 3.73's and my milaege just plain sucks!!! Had to loose at least 5 mpg. You will notice a difference. And from a 2.73 to 4.10 on an auto are you kidding me? You will be at like 3K rpm on the highway. Can we say "suck down gas".
And I wouldnt put 4.10 in a car unless you have a ton of power. You will have no power on top. I would go 3.55 with the auto and 3.73 with the 5 speed.

Just plain wrong in this case. Who went from 2.73 to 4.10 in an auto? The stock ratio in late model V6's isn't 2.73, it's 3.27, and after changing my wife's auto V6 to 4.10s the rpms don't reach 3K while cruising until about 80 mph. Mine doesn't reach 3K rpms with 4.10s while cruising in 5th gear until about 90 mph. That's very acceptable for daily drivers in my opinion, which is how our vehicles are used. While you have seen a mileage drop, we have not to any noticeable degree. Opinions and experiences after gear changes are bound to vary though, and yours is just as good as mine.

I agree, just make sure you get a T-lock so when you do burnouts you spin both tires
New Gears
