Gears

What is the difference in 3.73 and 4.10 gears as far as performance, gas mileage ect.....?

[blackgt04]

it depends on how u drive ur car. if u drive on the highway a lot u should go with the 3.73 gears, but if you want it to b a street/strip car and dont plan on doing a lot of highway driving than go with the 4.10s. u should gain gas mileage in the city with either 3.73s or 4.10s but will also lose gas mileage on the highway with either.

Just out of curiousity why not the 4.10 if i drive in the highway? and which one is better off the line

[blackgt04]

if u go with the 4.10s and drive on the highway a lot ur rpms are going to b worse than they would b with the 3.73s. the 4.10s shoulld give u a little better jump off the line.

if your runing a loud exhaust and do alot of highway driving you may grow to hate 4.10's, id go 3.55 or 3.73 but thats me.

i would personally recommend going with the 3.73s since u went with the exhaust setup that is on ur mods page site. the combination of the h-pipe, catback and the higher rpms(if u went with the 4.10s) will get annoying if u do a lot of highway driving.

id go with the 3.73's. Thats what I got and im glad i didnt get the 4.10's since i do a lot of driving across the state. the 3.73s are a good choice for you. the 4.10's would only benifit you on the track really.

[rob3980]

3.73's it will be then thanks everyone

I would have suggested the 4.10's, especially for a mod motor car.

You gotta ask yourself...Did I buy the Mustang as a performance car, or as a gas saver?

Agreed, but the difference in gas mileage between the 3.73 and 4.10 is negligible in a mod motor, so that isn't an excuse anymore.With a pushrod engine, it makes a hell of a difference, but this isn't the case.

I have 4.10s in my 01 vert and get 25 or so on hwy, it's a mustang, not a prius.:)

This isnt a mod motor car! its a V6 were talkin about

I just went from 3:55 to 3:73 and only saw a loss of about 2 miles per gallon .. not really a big deal as far far as I'm comcerned but I love the launch difference .. It was recommended to change my speedo gear too to keep the speedometer correct .. I think on my S197 it was like a $15 part but it might keep the cops from giving you a piece of paper

There really not a whole lot of difference in performance or mpg. I'd go 4.10 ESPECIALLY in a V6.
