Description
Upgrade OEM Gears. Are you looking to upgrade to a stronger set of rear gears? Then look no further than installing a set of genuine Ford Racing Gears in your Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, and race applications. Superior Quality. Manufactured in the USA, these Ford Racing Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and are completed in a black oxide finish to resist corrosion.

Application. This Ford Racing Ring and Pinion Gear set will fit all 2011 to 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.

Wow, Just what my Mustang was missing.

Love it, I didn't loose much in gas mileage (1-2mpg), but I gained a lot from the line. The car was pretty quick to begin with. Just a little slow from launch. Now its just right. I have excellent launch

Ford Racing 3.31 Gears: so far, well worth it!

So far, very pleased with the Ford Racing 3.31 gears. Still in the break in period, can't give it an Excellent for performance gain at this time. However, I can tell a difference in normal daily driving.

    Ford Racing 3.31 Gears: so far, well worth it!

    April 22, 2014

    So far, very pleased with the Ford Racing 3.31 gears. Still in the break in period, can't give it an Excellent for performance gain at this time. However, I can tell a difference in normal daily driving. The auto transmissions shifts a little harder and noticeable improvement going up small hills, stop/go traffic, passing and at highway speeds (about a 250 rpm increase). Little loss in average MPG (1.5 - 2.0), but well worth it compared to the 2.73 stock gears...any day of the week.

    How it should of been in the first place

    December 25, 2013

    So I bought a used V6 Auto with the 2.73 gears last summer. My use for the car is a daily driver with a 90-100 mile round trip 5 days a week depending on what errands I run before going home for the night and occasional fun in the canyons on the weekends. After about two months I was frustrated with the performance in stop and go traffic. When up to freeway cruising speeds the tall gears were great but, in dynamic traffic I felt the Mustang with the 2.73s made me look like a fool who kept missing shifts. The 2.73s were an invitation for slow drivers to fill the gap in front of me while the motor wound up only to be stuck driving below the speed limit behind them once back up to speed. The 3.31s cured that. I had already purchased a tuner/tune and while it made for a noticeable difference, it wasn't a complete solution. The V6 is fun & quick vehicle but is not a hot rod. I did not buy it to win races. I was worried about sacrificing MPG for unneeded performance gains. I was going back and forth between the 3.31s and the 3.55s. As soon as I made up my mind on future 18" wheels and reducing the diameter of my stock wheels and tires from 28" (215/65-17) I went with the 3.31s. Had I decided on on some 20s I might of opted for the 3.55s. I am happy with the result. I am a freeway cruiser, and a commuter. This gearing has made my drive more pleasurable and relaxing. My RPMs at 75 went from approximately 1850 to 2100. 2200-2250 at 80. But the response in the low gears is greatly improved and the response above 60 mph is noticeably quicker. The need to floor the gas pedal and have the exhaust announce the strain required to pass a slower vehicle is gone; now I just go. My freeway MPG decreased from 28-30 to 27-28. My overall MPG went from 27-29 to 26-28. Usually about a 1.5 mpg decrease. I should also state that I had purchased and replaced the differential with a Detroit TrueTrac, and added larger rear brake rotors at the same time. The rear end is now slightly heavier. I also purchased the Ford Racing pinion bearing kit, and new carrier bearings from American Muscle. I paid $275 to install it all and already had a tuner to change the gearing in the computer. American Muscle shipped everything fast and organized.
