      Product Information

      Features, Description, Reviews, Q&A, Specs & Installation


      • 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.

      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.

        5 2014 V6 - mark Installation Time: Weekend


        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 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!

      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???

      • These Ford Performance Ring Gear and Pinion Kit will provide quite a difference in performance, especially if you have been using 20 inch wheels with the factory gear ratio.

      Do I neccaserily have to buy the install kit 1 answer
      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

      Will I need all these accessories? I have a 2014 V6 with only 1,200 miles on it will I need all the accessories to install these gears? I'm also taking this to a shop to get them installed, so will I need the install and bearing kit? 2 answers
