Need some help deciding on gears for my auto.

3:73 OR 4:10 what do you guys think?

It's not my daily driver but it may become later. I do a lot of highway driving but really don't care about the motor noise. How much MPG will is lose with the 4:10 compare to the 3:15 I have right now. I'm leaning towards to 4:10 but would like some input.

I have a shop that will be doing the instal They charging $485+tx
I will also be welding my axle shaft the same time for around $200+tx

Are those decent price's?

 

Do you plan on installing FI? If so 3:73 and if not 4:10. I have run 4:10 on both and 1st gear doesn't really have a use never run a auto so others can pitch in

 

FI, Not anytime soon.

 

If you're doing a lot of highway driving and concerned about mileage, I say go for the 3.73s.

 

If you're a 5.0, your auto does not need gears! The first 2 tranny gears are extremely steep. The 3.15's are plenty for the rear. Get a good quality tune with a Circle D converter and the car will run low to mid 11's on drag radials. Without the converter you can still run high 11's to low 12's depending on conditions.

 

I had 3.15 gearing and recently changed to 3.73 so I can't comment on the 4.10. But what I can say, In my opinion, the 3.73 has made my car SO much more fun to drive. The 3.15 was boring. It took too long to wind up.

 

That's how I feel.

I think I will get the 3.73, But I'm Still not sure.

 

Are you in 4.6 or 5.0 cars? I can't see signatures; I'm on the app.

 

There's an option to turn on sigs for the app

 

Auto's love 373 gears.

 

I just got my car Saturday... And it is a MT82 with 3.73's... But first gear is SO quick I would think 4.10's would almost make it worthless...

 

13' 5.0 6 speed auto

 

It looks like it will be 4.10

 

Autos like 4.10s. My friend picked up. 25 with them. He has ran 11.47 woth gears X pipe tune and Tires.

 

Does he have any problem with traction?

 

I have 3.73's with my 6MT and Steeda 93 tune. Couldn't be happier.

 

4.10 it is...

Got most of the parts, Just waiting on Axle Seal and Differential Cover
Getting it done next week Friday, Along with welding the axle tubes and the reloc bracket.

Thanks for everyone's help.

 

Can't wait to hear how you like it. I want to do the same.

 

Ahhhh too bad, I have brand new in box 373's I would have let go for a c note.

 

What gears did you go with?
