I just got the appointment next Thursday (finally) for my 3.73s, was wondering if anyone had any regrets or dislikes about them.

I have 3.55 gears and to me it seems like the best of both world. It's a world of difference from 2.73 to 3.55, so that could be an option for you if you want to back out of 3.73. You will be able to tell the difference in your RPMs, but nothing that will make you nervous.

I got quoted 650$ gears and tax included, and for an extra 100$ he is going to install my SR lowering springs. Its a very reputable shop that only works on mustangs called mustang direct.

Canadian, I probably could have had it done cheaper but I went with a mustang specialist who does gears very often. My brother is a mechanic with 30 years experience and said he'd do it no problem but I know he doesn't do gears all that often, and my stang is my baby, so I just bit the bullet.

The only reason I wouldn't go with 3.73's is if you do the majority of your driving on the highway and care about gas mileage. From my experience in the past you won't notice much of a drop in city MPG it will just require more shifting. But from a performance aspect, can't go wrong with a good set of gears.

I personally will be doing 3.55's when the time comes since I do a lot of highway driving. However, I see most people getting worried about high RPM, etc as a cop-out with going to 3.73 gears. I think it's because we get acclimated with turning 1.5k RPMS's at 80mph, when most other cars are at 3k for the same speed, so when we read about the "huge jump" to 2700 rpm everyone gets nervous.

My opinion is Ford wanted a marketing ploy for the V6 to help with the last sales push of our gen cars. The result was they ended up castrating the car with these horrid 2.73 gears.

I hear ya bro! :) I actually don't find 2700 rpm's high but that's just me. If I'm at 2700 rpm's with my 3:73 gears doing 80 mph then 3:55's I'm guessing be 2400 rpm's give or take. 300 rpm's is not going to make a difference. I had debated this very thing when I had 2:73 gears. Should I go with 3:55 or 3:73 gears? Researched it for months and in the end so GLAD I went with my 3:73 gears.

Hindsight, I personally would of gone with 4:10 gears had I known back then what I know now. I don't track race, semi daily driver and all highway miles. We have 6 gears in our cars, its not like the 04 mustangs that have 4 gears. Big difference. A guy in my local mustang club has an 04 Gt with 4:10 gears and 4 speed automatic.

We have six speeds people. Ha ha ha!

I'm also at 2,000 RPM at a steady 80MPH

My 2012 cruises at 80 with my 2.73 rear. My Speed-o-meter is backed up with my GPS so I'm sure it is correct.

My choices were between 3.55, 3.73 or 3.90s.

my car has 51k miles i have driven 49k miles with 4:10 gears installed and havent had a single regret.. the only regret you might have with 3:73's is that you didnt get 4:10's instead lol

From what I hear its two heat cycles. I also heard that highway should b avoided during these cycles but where my car is I have no choice but to do some highway (30km) when I get home I will definitely follow whatever break in period and method they tell me. They are also well aware that I'm a little distance from the shop.

The type off driving would be more stop and go city driving, I'm not sure of the longevity of the cycle but when I pick up my car tomorrow I should be able to give you more specifics. They only do mustangs and that was a big reason why I went to this place.

What was your cost out the door total? Did you buy the whole kit from American muscle what addons did you pay for such as rebuild kit and how long did it take the shop to install them? ?

The gears are as quiet as the stock ones. I really couldn't have asked for more from these guys!!!

I stopped by my Ford dealer today. I was quoted 3 hours labor for the whole job. Labor here is $105 / hour. American Muscle has the gears (3.73) on sale. I love my 14 auto
convertible, but the transmission always hunting for the next highest gear is frustrating!

It would be nice to feel the power of the engine!
