3.90 gears or 4.10 gears?

01dutchGT · June 1st, 2007, 01:43 AM

I have a 2001 mustang gt 5 speed. I have 3.73 in it right now and im not happy at all. I want wake my mustang up and give it more pop off the line. I dont want to be sitting at 4000 rpm cruzin at 70 or 75 on highway so which gears would be the best. I have my mods listed on the bottom so let me know what to get. I also would like to know what website as well as what brand is the best to get.

I have 4.10's and at 80mph I'm at about 2800rpm's

DCstangGT · June 1st, 2007, 02:39 AM

I just ordered 4.10's a week ago and i cant wait for them. They will be installed on the 18th and ill have some new track numbers on the 22nd. The best price i found was on RPMOutlet.com. Get the FRPP 4.10's!!!

SWEET2KSTANG · June 1st, 2007, 03:20 AM

i have 4.10's and at 80 i am at 3000rpm's. for an n/a set up 4.10's are great. i have 4.10's and hate them with my set up.

ddashtrois · June 1st, 2007, 01:38 PM

ive taken my car on the highway with my 4.10s and it was fine. i mean, i was doing anywhere from 90-120 the whole time and i dont even think i went over 3000RPMS unless speeds were above 100mph... then again im sure u can throw it right into a calculator of some sort and and get a definitive answer

DrHolliday · June 1st, 2007, 02:38 PM

I voted 4.10's b/c ford racing doesn't make 3.90's.

Depending on what path you chose to go you might consider going lower.

With my set up I almost want to switch to 3.73's or even 3.55's

FOR POINT SIX · June 1st, 2007, 04:10 PM

4.10s or 4.30s, I am running 4.10s and think if I could do it all over I would go with 4.30s.

You two should trade.

rk_2000_Z/28 · June 1st, 2007, 05:39 PM

You are not going to be very happy with the difference if you just go from 3.73 to 3.90. I would go AT LEAST 4.10 (maybe smaller-numerically larger) just depending on what your future plans are. If you are planning any kind of FI I would stay away from any kind of steep gears, but if basic bolt-ons are it for you than yeah at least 4.10s

invisa stang · June 1st, 2007, 06:12 PM

also my friend has 4.10's on his mustang and they do some of the nastiest burnouts that i have ever seen

01silversnake · June 1st, 2007, 07:05 PM

i guess that it would depend on what you are doing.. I think that if you are going to stay NA then you need the 4.10 but if you arent then you should go the 3.90..The one problem is that Ford doesnt make the 3.90s so i guess that you would have to go with the motive gears and then i hear that they whine a lot..

Same here. or even 4.56s

MustangMatt96GT · June 1st, 2007, 10:32 PM

The Pro 5.0 gears have had a few good reviews, and they make 3.90s! But go 4.10s! All the places around me that have any knowledge about Mod Motors say that I should go 3.73s, and everyone hear that I have talked to say to go 4.10s! I am going to go 4.10s!

travis_afx · June 2nd, 2007, 04:27 AM

I have 4.10s and i love them but i've aslo read alot that people say if you plan on going FI then get 3.73's

That's exactly what I've heard.

GTsetGO · June 2nd, 2007, 08:57 AM

I have 410's and love them.

FOR POINT SIX · June 2nd, 2007, 03:30 PM

Wow the 4.10s are running away with this poll!!

codycat91 · January 23rd, 2012, 05:46 PM

Wow can't believe I'm the 1st person to post this... http://paladinmicro.com/pmicro.php#
Go 4.10s if you're staying n/a. I thought I was gonna stay n/a but plans have changed and I am now going to have 3.55's
