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

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 2012 V8 Mustangs including GT, Bullitt, Mach 1, Cobra and the 2011-2014 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 drivability

Tore up a 3.90 ratio set and put this instead! In my opinion felt better! Did not lose the top end like before!

Nice!

Just what my car needed. Combined with my supercharger, I can really feel the torque. 3.73s are the way to go.

    3.73 for my 98 gt

    Was very impressed with the difference it made with launching the car and acceleration through the first 2 gears.. Especially over the stock 2.73 gear. I put this on a stock 98 gt paired with a great set of tires and I was now able to beat my friends fox with heads cams out of the whole! Then he eventually pulled me in third. Great bang for your buck...

    Good buy for any guy (or gal)

    Bought gears, install kit, and girdle a few weeks ago and had them professionally installed. Very happy with the gears and how well my car pulls now. If you want to make your car a little quicker without major cash, these gears are an excellent choice.

    Can you say IMPROVEMEMT?

    Installed on my 03 GT. Install price was $200 trust me if you dont know what you are doing with the shims and setting the backlash have a pro install these, but lauch is much improved 2nd gear is nasty. 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!

    04GT 3.73gears

    DONT FEAR THE GEAR! The perfect gear for a street car. Decent RPMs on the highway and crazy excelleration through first 3gears. Have them installed by an experiance tech who has done these before. Its hard to keep my foot out of it now!
