    Features & Details

    • Ford Racing Quality
    • Strong Forged Construction
    • 3.73 Gear Ratio
    • 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 2011-2014 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.

    What do I need to get these installed at a shop? I have a 2014 V6 and I'm taking these straight to a shop to get them installed, so what accessories to I absoutly need to get them installed?

    • You would need 3 Qt. if fluid with friction additive in them, or fluid and with separate friction additive. That's all you need for the installation done by a shop.

    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 have 20” wheels and didn’t think it was gonna make this huge difference in performance would the 3.73 geas make any difference at all with the 20”s???

    Do I neccaserily have to buy the install kit

    • The Ford Performance 3.73 Gears do not necessarily require the installation kit, however, it is highly recommended. Giving your differential a refresh will help ensure smooth operation and prolong to life of the unit.

    I plan on adding 3.73 gears on my 2011 V6, and a procharger, n upgrading some interals. Do i need to upgrade my drive shaft? 1 answer
    Well I read through most the questions and I didn't find a *Solid* answer. 1. To have these 3.73's installed in my 2011 V6 do I *need* both the "Installation and Bearing Kit" and the "Add 8.8in Rear Gear Pinion Bearing" or is that redundant? 2. "Add Traction-LOK Rebuild Kit w/ Carbon Discs" is this needed on Automatics? And more importantly is this needed for V6 Mustangs? The description seems to be talking about how it helps with more Torque but us V6 owners typically don't see above 400 HP/TQ so why would I need to spend the cash on this? More importantly is Question #1 though, thank you so much! I'll purchase once I get a response! Thanks!! 1 answer

      Quicker

      It is definitely quicker but with 325 HP , currently , I figured without a brake torque it would smoke the tires a bit out of the hole , it really doesn't . My BAMA tuner should be here tomorrow so hopefully I will get everything synced and wake the Pony up a bit more .

      Trying to figure out the whine

      Paid almost $500 to get them installed and upon deceleration I get a horrible whine/howl. The shop says it's the gear but I'm thinking backlash, can only give 3 stars based off what I have been told.

      Smooth Shift in Gears

      I had a local shop (Greater Philly) do the install. Seamless transition. Only issue pertains to the camshaft, which will need to be replaced with a one-piece to accommodate the big difference in rotations. Solid part -- I have no complaints or concerns.

      Noisy in '14 gt

      Ford must have changed something to the rear end housing..my 3.73 that i bought new from am are very noisy when i let off the gas..i read many online complaints about putting 3.73 in my body style mustang,even factory installed 3.73 making noise..I changed all the shims to get the right feel because the ring gear it just too snug even though the backlash is perfect..I havent heard anyone complaining about 3.55 gears making these noises so i ordered a set from am and will install them..its not the gears i believe its the housing thats manufactured wrong,but thats my opinion

      Great Product!

      I have had the gears in for about 500 miles now, so far no issues. I came from a 3.31 to the 3.73's and let me tell you theres a big difference! The rpms are a lot higher and I'm probably getting worse gas mileage but i also can't keep my foot off the gas pedal!

      They are awesome!

      Since ive gotten these gears on my v6 automatic its opened the car up. I can now do burnouts unlike before given because of the lower end power these gears give you. Gas mileage isnt anything to worry about i havent seen a major decrease worth worrying about. If your looking into these id go for it. Installation cost me $415 also cause i had a bad bearing of some sort.

      I have a 2013 v6 mustang. All I did was put 3.73 gears and a basic 93 octane tune in it, and on the same day the gears were installed....... Well not sure how far into that I can go. But I will say it will pull on a new ss camaro with the mufflers cut off.

      THE next upgrade you should do!

      Get your tuner first (you will need it), then upgrade your gears next! Went from the weak 2.73 gears to these and you can truly feel the difference from 0-40. My car feels like it wants to take off. and 0-60 times have improved greatly. Tuning afterwards is a must. I would recommend you also swap out your stock drive shaft along with the gears, especially since you will certainly want to push your stang with these. If anyone tells you they cant tell much of a difference, I would dismiss their opinion...the driveability and torque down low is considerable!

      Worth Every Cent

      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.

      Big Change

      A big change in acceleration capability was definitely noticed right away. I went from a 2.73:1 to a 3.73:1 gear ratio. It was like a 33% kick in the rear.

      Auto tran re-think

      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

      Waking up the Pony

      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.

      Perfect all around gear ratio.

      Had gears professionally installed. No issues with noise or vibration. Still taking it easy breaking in the new gears but very noticeable performance gain. Didn't seem to affect gas mileage with normal driving. Best bang for the buck of any mod so far.

      2011 V6 3.73 gears

      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.

      Best mod yet !

      I have C&L cai and tune. Installation of these 3.73 turned my v6 into a monster. You get into your power range quicker than those mpg-loving-2.73s. No longer do I lose street races against fellow v6 camaros and 350z. My only draw back is that I didn't update my tune after I had these gears installed and my car was shifting at the wrong points. Once I got my tune updated is when I saw max benefits. However I now have gear whine because I went so long without it updated. No biggy. The benefits far outweighs gear whine. Just make sure you get your tune updated before you drive. I floor it in the city so I don't know those mpgs but highway i went from 34 down to 30.8. Not much loss at all, especially from stock. GET THESE GEARS ! install = 375
