Description


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 3.55 Mustang ring and pinion gears feature a super strong forged construction, CNC cut & lapped gear teeth, and a black oxide finish to resist corrosion.

Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a Ford Racing Speedometer Recalibration Tool is an inexpensive way to fix this issue.

Application. This Ford Racing Ring and Pinion Gear set will fit all 1986 to 2014 V8 Mustangs including GT, Bullitt, Mach 1, Cobra and the 11-14 V6 Mustangs equipped with the 8.8" rear end. 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.

Great compromise

I bought the v6 for MPG but realized there was potential to maintain some MPG but get more pull. I have the bama tuner 91r on my car as well. Love the gain down low and freeway is fun too. Cruising at

Q & A Ask a Question

2014 V6 manaul with 273 gears to a 373 gears I have a 2014 V6 Mustang with a 6 speed manual with 273 gears. Will the 373 gears be too much for the V6 ? I have already a CAI, Magna Flows, Airaid Throttle Body Spacer, BBK 73mm Throttle Body and a Bama Tuner. Also with the Bama Tuner do I need to buy the tool to recalibrate my speedometer ? When ordering how do I tell if my rear is a 8.8 or are all the 2011- 2014 the same size rear.. Also how must lost of mpg will I lose approx. I'm getting 32.4 now.

    Great compromise

    I bought the v6 for MPG but realized there was potential to maintain some MPG but get more pull. I have the bama tuner 91r on my car as well. Love the gain down low and freeway is fun too. Cruising at 80mph the rpms are at 2400 to 2500 and it makes it a tad more involved to cruise than before but love the gains.

    Best bang for the buck

    The 2.73 gears in my 2012 Mustang V6 6-Speed were great for good gas mileage, but terrible for performance. I purchased these Ford Racing 3.55 gears and had them installed by a local shop with a new bearing kit and the car is a different animal. I have raced many S197 Mustang GT's at the track and have taken quite a few down. The 3.7 is no slouch and these 3.55's make it shine. The cars best time at the track was 13.5 @105mph and the gears are what mostly got me there. I can still get great gas mileage with them and they have great driveability around town. Buy these gears, no whine or noise, you won't be disappointed.

    11' v6 automatic with 3:55 installed

    3:55 gear install was in conjunction with Eibach kit and Bama tune. (air intake and exhaust already done). As I was installing the Eibach kit, I spent the extra ten minutes and dropped the axle, took to local shop for gear install. Two hours labor (160.00) with me providing; gears, install kit + bearing (all from AM). Shop commented the Ford Racing gears and best due to being stronger and bevel cut which reduces gear noise. After install, MUCH faster off the line, 2100 rpm at 65-70 mph. Gas milage has dropped 2 mpg. Still getting 20+ mpg and the stang is very fast now (handles great too). Thumbs up. I worried the 3:73 gears would be too much (rpm) for freeway use. Glad I went with 3:55, I would not want any higher rpm for freeway driving. Plenty tall enough for off the line, first gear is used up very quickly.
