3:55 gears

[nctrader77]

I purchased a set of 3:55 gears, out of a new Mach I, for my 04 GT. Now I am wondering if I will see enough gain to justify the install. I did not want to go to a 4:10, for fuel consumption concerns. What do you guys think? Ditch the install, cut my losses, or go ahead and install the 3:55's?

Thanks

4.10s. I don't see a point in going from 3.27s to 3.55s.

3.55s in your GT wouldnt do a whole lot, upgrading from a 3.27 rearend. 4.10s would put your car right in its powerband, and if you drive normally you'll only lose 1-2 mpg. Sell the 3.55s for whatever you can get and put that towards 4.10s. If you had a 94-98 GT, i'd say 3.55s all the way because the HP and torque peaks at lower rpms, but the newer GTs powerband is really above 4000. Just my 2 cents

there's not going to be much difference at all. A little yes, but I'd go with 3.73s at the minimum.

if you can ditch 100 bucks two times (thats the cost of install around here) then go for it, at the least maybe it will get you chompin at the bit for 4:10s or 3:73s or whatever.

I thought that the 04 GT's came with 3.55's. Thats what i heard anyway. But i am guessing that it is wrong.

 

[stangGT97]

if you have the 3650 tranny, you have a 3.27 gear ratio stock in the 04. The '05s come with 3.55s, and so did the 03-04 Cobras

373

don't waste the money on the install of the 3:55s, sell them at get 3:73's if not 4:10's
goodluck !

 

[triggz]

you wont feel a thing. 4.10s didnt feel as near dif as i thought it would.

my buddy put 4.30s in his and he doesnt tach that high really.

4.10s or 4.30s are the way to go.

I love my 4.10's!

4.10's...enuf said.

 

[dmarco_4u]

you are just throwing your money away,
you will NOT feel the difference from 3.25 to 3.55's,
DONT FEAR THE GEAR!
ARE YOU SCARED? JUST SAY YOU ARE SCARED!!

Despit what everybody says you will!!! feel the dirference going to 3:55s i know because i had them. Its not a big defference but its there. I switched to 3:73s because i had the chance to do it for free. And i wanted a little more. I was happy with the 3:55s though. ITs all how you drive. I am really happy with the 3:73s and i personally would'nt want to go any steeper.

I currently have 3.55s in my 99 Gt and I can tell a slight difference in acceleration. I do alot of city driving and it allows me to leave the lights without using the clutch so much.

 

[mrvax]

I agree with the majority. Go with 4.10's unless you are a highway driver (me), a snow storm driver (me also). I'm happy with the 3.73s for my car and would strongly suggest taking a pass on the 3.55's.

04 GT's do come with 3:55's.

I just checked the specs with MM&FF.

That is a misprint, they all come with 3.27. Only mach 1s come woth the 3.55. If you have an 04 you can look at the rear end to see.

4.10s or 4.30s

Why do all of the 4.10 lovers think that 3.27s suck so bad?

My 1991 GT had 2.73 w/5-speed only option was 3.08. One of my LT1's had 3.23 and another 2.73.

I myself would rather have 3.55 or 3.73 in my GT.

IMO 4.10 suck and make a nice car feel like junk. I have raced a GT w/4.10's and was unimpressed.
