Gear whine...

orangestanggt3 · July 10th, 2007, 03:49 PM

what gear ratio would you suggest?

gills99stang · July 11th, 2007, 10:41 AM

Well.... are you auto or manual? Planning on FI anytime in the future? It all depends.

orangestanggt3 · July 11th, 2007, 10:53 AM

it is manual what is FI?

gills99stang · July 11th, 2007, 10:55 AM

FI = Forced Induction (i.e. turbocharger, supercharger)

I have a manual, no FI, and I have 4:10 gears and I love them. That being said, if you plan on going FI in the future I would go with 3:73 gears, but that's just my $0.02.

orangestanggt3 · July 11th, 2007, 11:22 AM

so if im going to have FI at some point then i should go with 3:73 why do you say that?

gills99stang · July 11th, 2007, 11:33 AM

...because IMO a manual car with FI and 4:10 gears makes 1st gear useless....

orangestanggt3 · July 11th, 2007, 11:45 AM

ok so i should go with 3:73 who has good 3:73 and where can i get them

MustangMatt96GT · July 11th, 2007, 07:16 PM

FRPP

orangestanggt3 · July 12th, 2007, 09:50 AM

do they have the best? and about how much would they be?

MustangMatt96GT · July 12th, 2007, 10:53 AM

Ford Racing Performance Parts are the best gears you can get and for 3.73s I have seen them around 200

orangestanggt3 · July 12th, 2007, 11:21 AM

and then im prob going to need the rebuild kit

orangestanggt3 · July 13th, 2007, 09:46 AM

when i replace my gears in my 04 gt is it a good idea to get a rebuild kit as well?

04gt · July 15th, 2007, 02:35 PM

I just put FRPP 4.10's in my 04 GT... I bought the gear package on americanmuscle.com with the oil, gears, and diablo tuner... then I got the bearing/rebuild kit too. By the time It was all shipped to my door and I got it installed it was roughly 1000-1100 dollars canadian. Mind you thats with the 400 dollar tuner included though but I'm more then happy with the gears and my gas mileage did not go down at all and I haven't been easy on it this last tank.
