  • Ford Racing quality
  • Strong forged construction

  • 8.8" Ring Gear Diameter
  • For street or track use
  • Fits 2011-2014 V6 Mustangs
Improve ET's and low end torque. Are you looking to get more low end grunt off the line and lower ET's at the same time? Then look no further than installing a set of steeper gears in your Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use. Superior Quality. These Ford Racing 3.73 Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion.

Application. This Ford Racing Ring and Pinion Gear set will fit all 2011-2013+ V6 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please see drop down option above.

Technical Note. Installation costs will vary, but a good rule of thumb is between $250 and $300. Be sure to work with a reliable shop that you trust for installations. You can also save money on your installation labor by having your Trac-Lok rebuilt at the same time as your gears are installed, see drop down option above.

Can the differential gears be changed? I have a 2012 Mustang V6 convertable. I want to change the 2.70 to 3.31 or lower. The Ford dealer said that Ford told them that they cannot do this on a convertable. There is something to do with the computer program and warrenty. Even with warrenty aside, the Ford dealer siad that they cannot do a gear swap on a convertable. Can you tell me what I need to do or who I need to talk to to make this happed. I have talked with 2 others in the same place as me and are anxious for your help. Thanks

  • Yes. I had it done. I even talked to a dealer and they said they would for 700. I did it with a local mechanic (ast certified) for 550 total with tax. This was like 200 over quote. Anyhow, it whines badly especially on deceleration. After having the mechanic try to adjust gears, they still whine. He says the teeth are lined up perfectly but that after some research he figured out it is likely the differential in these rear ends. So, to be safe change the differential at the same time ( muh cheaper to install while they have it open) a ford racing dif only costs like 250-300. It is worth it. The whine sucks. But the car is much quicker! Stock you can't order a mustang v6 convertible with steeper gears. Aftermarket you can install them.

I was wondering how the 3.73 gears work with Automatic Transmission 2012 V6 Premium? Seems like most have purchased a Pony with Manual Transmission. I have an automatic, so i was wondering how these gears perform in an automatic Transmission?

  • I have a 2012 v6 auto and I got the Ford Racing 3.73 gears. These gears were the best thing I have purchased for my car yet. It provides much more torque down low. In my auto I do better 1st gear burn outs from a stop and I now also chirp the tires going into 2nd!

    Man these gears are awesome! Car pulls super hard in first and second gear. Rpms stay high so you stay in the power band of the vehicle. I improved my 60ft time from 2.0 to 1.8 with the gears and regular high performance street tires. If you are looking for more low end power get these gears, if your looking to save the good gas milage, stay away from these. My mpg dropped about 4-5 mpg but that's because I don't keep my foot out of it. I can't, it's just too fun to stomp it and hang on lol!! Get these gears, best mod I have done yet. I run 13.24 @ 105mph on just an intake, sct tuner, exhaust and gears. Next mod will be control arms and drag radials. I will run 12s!

    3.73 gears are the best upgrade for the price (2012 v6)

    January 27, 2012

    3.73 gears are easily the best bang for your buck. They make the car much more fun to drive and make driving a v6 that more rewarding. You will need to buy 3 quarts of gear oil (I used Royal Purple 75w140). For all the parts and the gear oil it will cost you about $275 plus allow $200 - $350 for install, trust me you will need these installed by a shop unless you are a professional mechanic. They will lower your gas mileage by about 3mpg highway and 1-2 mpg city. Especially since you wont be able to keep your right foot out of it! Also, for all you 11-12 v6 owners after having these installed i test drove a 2011 gt just for a comparison and i can honestly say the gt didn't pull any harder. Definitely recommend these.

    Waking up the Pony

    January 29, 2013

    It has been said before and I will say it again, one of the best mods if not the best one for you Mustang. These gears are of high quality, no whine with them, installation was about 4 hours. And what a difference it makes in waking up your car, these should be factory standard for these cars. It improved the take off for my 2011 Automatic V6 convetible, thus improving 0-60 time. These along with the CAI and the Bama tuner (needed also to corret speedometer) have transformed my car into a beast. Highly recomended, its a must for every mustang.

Went to the local strip with is an 1/8 mile track and ran 9 flat with the help of the AM CAI. Killed a few Comaros in the process and isn't that what we are all after? Buy it stop reading! GO!

    2011 V6 3.73 gears

    August 17, 2012

    summary...just get them I researched and debated for a while what gears for my V-6. I had 2000 GT with 4.10, 1985 with 4.30, 2005 with 3.55 and 1994 with 3.73. The 3.73 are great for the 2011 V6, They added very noticeable quickness and zip to the car. 1st gear is a bit too low and truck like, but 2nd to 6th (I have a manual) are perfect. With the stock 2.73's I seldom used 5 and 6, even on highway crusing, sometimes would not use 6th. I'm glad I didn't buy 4.10, I believe they would be too much. They are great on the other mustangs I had, but the 2011 has lower transmission gearing than the older manual trans.

    Big difference but gear whine without differential change

    May 14, 2012

    Wow. This really makes the car move. Big difference. I got mine installed at a trusted shop. However, my total install price came to $533 with taxes and all. I took the car back because of the gear whine on deceleration. They adjusted the positioning slightly but could not get rid of the whine. They said the gear teeth were making perfect grooves. They also said that they researched this car's rear end and found that 80% of installs have this problem. It seems the only way to get rid of the whine is to install a new differential with the gears. Regardless, the acceleration is worth this cost and whine.

    Auto tran re-think

    February 13, 2013

    I have 2013 v6 auto with Bama Tune. Stock has 3.31 gears, then i decided to go with 3.73 gears. The improvement is noticeable , acceleration faster, car seem lighter. But not that much, some reviews say 3.73 transform the 3.7 v6 into beast ( not really ). With automatic , you should go with 4.10 and feel the true beast. Gas millage is not hurt much. My average is 18.3 before for city and 25 freeway. Now with 3.73s its up to 20.0 MPG for city and 23 for FWY. This is a good product anyway. Recommended

    Worth Every Cent

    December 22, 2013

    I have had these gears installed for almost three months now, And I love them. I had the stock 2.73s before I upgraded to these 3.73s. The old gears were simply to long, first in particular. These gears really have made my 3.7 a lot more energetic. The car pulls hard in every gear now. If I launch my stang at anything over 2500rpm, then I will spin through first, sometimes even second, and possibly into third. These gears and my other mods really have made my little 3.7 into a monster. However, my revs have increased to about 2500 at 70mph on the highway, which has hurt my mpg. If you do a lot of highway driving, then I would suggest higher gears like 3.55s or 3.31s. If your main concern is acceleration, then these 3.73s are a excellent choice. Also, I have not noticed any wine.
