Got 3.73's?? Get in

NoKturnaL · 05-15-2005, 06:44 AM

I hear that 4.10's is the way to go ...unless you do alot of highway driving or have a supercharger........

My question is....when u switched from the stock gears to the 3.73 gear did the car accel faster? did u notice a difference? Is it more alive? I just wanna know if its worth getting the 3.73 or just staying with stock gears...

silvergt · 05-15-2005, 07:02 AM

I have the 4.10s in my auto which is supposed to be comparable to 3.73s in a 5 speed, but a friend of mine put 3.73s and he noticed a big difference in accelerating. When i was shopping around for gears i emailed steeda and a few other companies and asked their techs what they recommend for my application and they were very helpful and knowledgable.

buddyabe · 05-15-2005, 08:08 AM

I Installed 3.73 Gears In My Auto And Noticed A Huge Gain In Acceleration And Yet The Car Was Very Streetable. I Installed A Set Of 4.10 Gears And Felt A Little More Acceleration,but Didn't Care For The Extra Rpms The Engine Now Runs. I Will Be Installing A Set Of 3.90 Gears This Week To Split The Difference (my 4.10 Gears Were Noisey And The Rear End Had To Come Apart Anyway's) If The 3.90 Gears Werent Available I Would Rather Have 3.73 Gears For A Daily Driver. The 02 And Newer 5 Speeds Do Run A Lot Less Rpms In 5th Than The Automatic Trans Cars Though. The Gear Replacement Will Be One Of The Best Bangs For The Buck You Can Do,it Makes The Car A Whole New Animal!

I put 3.73's on my 02 Automatic and felt a great improvement. Of course it's never enough so now I run 4.30's.
I was able to run 13.712 with the 3.73's and a few bolt on's.

*madmatt* · 05-15-2005, 10:42 AM

Yes, youll notice a huge improvement with the 3.73s, but, unless you are getting a blower, get the 4.10s. If you are getting a supercharger, then yes, get the 3.73s. They are a great gear and Ive had tons of fun with them.

Blue03gt · 05-15-2005, 06:37 PM

Motive 3.90's!!!!!!!! :notworthy

imported_01_Gt · 05-15-2005, 06:49 PM

Mods are in my sig.....

yay 3.73 it is.

Samsstang · 05-16-2005, 07:38 AM

I would say for your set-up and future S/C you cant go wrong with 3:73s! That was my first gear swap and it felt great and driveability is awesome still! I had the FRPP brand !No noise whats so ever very good gears! I went with Richmond 4:10 gears on a friends recomendations cause they are very strong but they whine :angry3: feel good though cause my car is not S/C

so if a car was staying N/A...then 4.10's would be the best choice, and 3.73 is a waste of time and money pretty much?

bluemang417 · 05-16-2005, 09:54 AM

go with 373s if going to have a power adder of any kind in future regardless of transmission and 410s or 430s if going na

I wouldnt say a waste of time! especially if you still have the stock gears, like I said they do make a noticeable difference! the only reason I went to 4:10s is cause i hit a curb a while back and decided to do my whole rear end: new posi, axles, and ring and pinion. Based of a friends recommendation jumped to the 4:10s if I was to doit over i would stay with the FRPP brand. If you dont like the extra RPMs stay 3:73s! I like them cause on the Motor the car pulls nice around town, I run nitrous @ the track and i find myself short shifting and goin thru the gears real quick :icon_shak

cumstang02 · 05-16-2005, 10:53 AM

I went with the 3.90's but i plan on running nitrous along with a few of my other mods. My friends love there 4.10's but they run N/A.

gtnumber2 · 05-17-2005, 07:36 AM

the 3.90s are just 100 rpm more then the 3.73s and pull a lot harder, imo the best of all worlds.

Ponyman460 · 05-17-2005, 08:18 AM

I love my 3.73's! They were a very good SOTP enhancement!

Mrktre02 · 05-17-2005, 09:09 AM

i had 4:10 on my 95 convertable, and it was great, but i'm working on my 02 GT and was thinking more along the lines of 3:73... I need more top end speed.. any one have any suggestions or cautions?

MachGT · 05-17-2005, 09:23 AM

4.10s for NA, 3.73 for a blower car. Stock gears wouldn't be bad with a roots blower or turbo setup.

Nitrous loves gears as well so at least 4.10s with nitrous.

I have my 3.73's and a vortech blower. It's pretty much the perfect gear

Ponyman460 · 05-17-2005, 09:27 AM

did I forget to mention I have a set of 3.73's (a second set) for sale?

04redgt · 05-23-2005, 05:08 PM

this is the first gear swap ive been contemplating, i drive the thruway 50 miles each day to work, 65 to 75mph, have an automatic, ive been told by mechanics at a ford dealer to go with 3.73 gears, dont do alot of city driving but a little here and there, ponyman460 still have the extra set? complete with? how much?

Ponyman460 · 05-23-2005, 06:06 PM

just the gears...came off a ford factory vehicle with 8500 miles. looking for 100 for them. thanks for asking. I love mine on the highway, not too much for a dd IMO.

white99gt · 05-23-2005, 07:32 PM

EIther gear will be a big help.
Personally ive run 3:73's since 99 .And ive never had one regreat about getting them.

N/a it was a nice sotp feel,and with a blower they felt just as good.
The difference on the highway is 200 rpms between the two(just add 200 rpms for every step up in gear from stock) .SO its really up to you.

fallstar · 05-24-2005, 08:06 AM

I've got a set of FRPP 3.73s sitting in my room but I'm thinking that 3.90s would be better, even with the supercharger.

dom · 05-24-2005, 01:28 PM

3.73 and 3.90 you will not feel much difference. use the 3.73 because they are frpp. i use 3.73 with my blower combo

04redgt · 05-24-2005, 05:22 PM

well if i buy the brg kit, crush sleeve, nut and seals that would come out to around 150.00 i appreciate the reply but ive have seen quite a few new complete kits for 150.00, ford racing kits, i might consider if the price was alittle more competitive, what do you think? any pictures so i could see the gears?

Ponyman460 · 05-24-2005, 06:49 PM

wont go any lower than 80 plus shipping....thats more than 30% off for only 8500 miles

I'll work on pics for tomorrow some time
