This has been asked 3 trillion times, go to google and search, the answer is not 3.73, he doesn't even know what if you have an AOD or a 5 speed.

3.73's have no kick? I beg to differ.

in my opinion go 4.10 or just leave it stock, doing less gear loses you performance and NOTHING else

MPG is not even affected, its how you drive it

every one of my 5.0's got 21-24 MPG if i drove it cool whether they had 2.73 or 4.10

each bump in gearset will run you about 250 rpms higher then the one below it in any given gear. thats a rough number, but your looking at 1000 rpms higher total in any given gear if you swap from 2.73 to 4.10

here are some facts, to dispell some of the retarded rumors you may have heard...mostly from people who used 3.55 and want you to waste your money too cuz they feel bad about themselves

1) you will NOT have to shift into 5th in a 1/4 mile with 4.10's

2) you will NOT tach 4k doing 60 you tach about 3000 doing 70-75

3) you will NOT get 10 mpg, well you will,,,,cuz you'll be in it all the time. but if you drive cool you'll do 21 mpg

4) a stock 3.73 car CANNOT lift a tire on slicks, but a stock 4.10 car WILL lift about 6" (that alone should sway you)

so although the gearing is close...4.10 is optimal for a NA car looking to squeeze every tenth it can

its not worth bumping a single gearset, so make sure you do it right the first time


thats my 2 cents, im on my 6th stang and i will NEVER use anything but 4.10

*** and before someone says "i used 3.55 and it was way better than stock" ***

well of course it was.....and if a starving ethiopian found a rotten big mac he'd eat it and love it, but it doesnt make it delicious. it just makes it "better than starving"
