2014 V6 Mustang Ring Gear and Pinion Kit

Hello Everyone, I am from detroit this is my first post here at the TMS. I drive a 2014 V6 manual mustang. I was planning on putting on the Ford Performance Ring Gear and Pinion Kit - 4.10 Gears. Wanted to understand the effects its going to have on the car? I do know my miles per gallon will go low, but apart from that what gains I can expect out of it? Is it worth the change?

Thank you all.

It's my understanding that gear sets like the one your looking at are all about acceleration. The higher the ratio, the quicker off the line and the faster you can accelerate. The trade off is your top speed will decrease and you will lose some MPG. If your going to do more drag/autocross or track visits with your car then the 4.10 setup will be a great option. But if your car will be more of a daily driver with occasional track use I wouldn't go more the 3.73. Here's a link with more info https://www.americanmuscle.com/musta...ial-gears.html

What gear ratio do you have now?

the trade off is higher rpm at every speed, and shorter gearing overall. Meaning you have to shift more often because motor revs faster.

4.10's are going to make first gear useless, with the manual I would stay with 3.55's or 3.73's.

Change your gears, you'll love it Look at the little white sticker on the right side of the pumpkin, it will have the gear ratio on it. You'll need something like an SCT hand held tuner so you can make the speedometer right. Buy a tune from Steeda, Bama or MPT too

I use it as a daily driver, with some track sessions.

If I understand correctly, with the increase in ratio 3.73's or 4.10's my throw is going down significantly correct? Will the stock shifter handle it?

I just checked my VIN and found out that my axle ratio is 2.73. It is going to be a difference if I change it to 3.55 or 3.73.

no, this has nothing do with shift throw distance. That won’t change at all. It changes engine speed at every vehicle speed. If now you’re at 1800 rpm in 6th at 70 with you now will be closer to 3000rpm with 4:10s

think of it like this. 2.73 means that the driveshaft rotates 2.73 times the speed of the wheels. 4.10 means 4.1 times. Engine has to spin faster at same wheel speeds.

Which would help me add some gain, long tube headers or shorty headers?

You should start a new thread when you change subjects - people interested in talking about exhaust systems aren't looking in threads about ring and pinion sets.

In general, long tube headers will give the most performance gains in naturally aspirated engines while shorty headers will produce smaller gains but are easier to install and don't affect ground clearance as much.

You need to slow down and think about what you are doing or going to do to your Mustang. If you read and research 'most' people have gotten rid of their Roush Axlebacks when going with long tube headers because they become too loud . My Magnaflow Street series became almost 1/3rd louder when I installed my long tubes with a catted x-pipe . Still not to loud but almost
