I'm looking to install gears in my 03 GT 5spd soon. Ive read a thousand post on 3.73 and 4.10 gears. There are so many mixed reviews about them. Most complain that 4.10's are too much and the others seem to say 3.73's did not offer what they were looking for. Anyone using the 3.90 gears from Motive are any other manufactures??? Seems like they would be a nice in between ratio. Any advice on the 3.90's would be appreciated.

 

I installed 3.73 in my 01 convert with auto,they made a huge improvement. I have a set of 4.10 that I'm debating on installing. I believe that the lighter coupe with a five speed would be happier with the 3.73 set altough the 3.90 gears do sound like a nice compromise even for my set up

 

im going with 3.73 or 3.90's. Having 4.10's would stop me from eventually getting a supercharger.

 

I think i'll be differen't and try the 3.90's. Iill probably get them in late feb. If anyone recomends staying away please let me know.

 

If you plan on staying NA then I would go with 4:10's. I don't really think the difference in the two is worth worrying about. 3.90-4.10 is not that much. You can always go with the 4.10's and run a 26" slick at the track and then put on a 28" tall tire for the street..pretty much best of both worlds.

Don't listen to Adam his car is slow.

 

I remember 3.90 gears on cars in the 70's. I have not seen them advertised for late model mustangs. If they are available, let me know.

If so, I'd be interested in them. :icon_thum

 

Motive makes a 3.90, list for 175.00.

 

What was the DA on your 12.89 run? :icon_king

No Dean is telling the truth about the 1300 ft DA. Thing is when he is done with his run, the DA is only 25 ft because his track is on a hill.

 

i bought 3.90s but not installed yet, but there is a member here called jimbo who posted his review a few posts down.

 

We sell the 3.90s on our site... lol

MustangTuning.com.


I recommend them for anyone on the fence deciding between 3.73 or 4.10

thats were i got mine. ive been in a car with both 3.90s and 4.10s and you cant tell the difference in how they pull.

 

well my mind is made up, I'm going to get the 3.90's and after i order my Venom 1000 kit in Feb from MT, if everything goes smooth with that order, ill get the Motive 3.90's from mustangtuning also.

 

Ssshhhh. Let's keep that quiet.
