[dSgMach1]

I haven't drove an auto on hwy but 4.10s felt good around town . I have a 5spd and like 4.10s

well 4.10s youd deffinetly notice the rpms on the highway. if you do alot of highway cruising and dont want to lose mph on the highway then id do 3.73s.

I think I'll agree...I loveee the feel of 4.10s... but 5th gear now almost feels like 4th did with 3.27s. Also, I think my gas mileage literally went to s**t within the past week of install

DONT FEAR THE GEAR!!!!!!! 4.10's all the way! I went with them and I love them.

I have 3.73's real nice. thinking of putting the 4.10's back in. At 65 mph in overdrive I see 2000 - 2200 rpm. Also a Mach-o-matic.

Yup most of the mach 1 guys say 4.10 at the least. I was planning on putting in 4.10s. But I got a Vortech instead

I just had 4:10 gears installed with high flo cats and magna pacs plus a SCT tune and on my 2002 gt auto. And its amazing it feels like a different car.

410s FTW!!!

 

[matt07gt]

I've got 4.10s in my auto GT. Go for it!!! You will not regret it at all.

lol 4.10 def

 

[blackfoxgt]

4.10s runs good for me

 

[Rob04Mach1]

For an Auto I think 4.10's are the move

I put 4.10's in my 99 Procharged GT and with the Std Trans I felt it was too much shifting, but for non SC Auto I think you will be pleasantly surprised

 

[Chuckie B]

4.10's

 

[Cheeeto]

Unrealford put 3:73's in his 04 automatic and he wishes he would have gone to 4:10's...just saying

 

[Unrealford]

I love 3.73s for daily driver lots of performance gained,but for mostly track use 4.10s are the way,@ 65mph I was at 2800 rpm...

 

[modularmustang]

i have 4.10's in my SRA right now and I'm swapping in a IRS in a few weeks with 3.27s, guess what I'm going to swap in to replace the 3.27s? haha

 

[dSgMach1]

So basically don't fear the gear? Do 4.10s ??
