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 Cobra. Ford Racing Ring and Pinion Gears are perfect for street, road, or race use.

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.

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 1994-2004 SVT Cobra Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, 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.

    3.55 cobra gear

    Very happy to have taken the 4.10 out and replaced it with this 3.55. Happy to get my rpms down and stop wearing out my motor.

    Excellent!!!!

    I was worried about the gears being made by a different manufacturer, but I worried for nothing. The gear teeth are cut a little different than the previous Ford Racing gears; nevertheless, they performed flawlessly and without noise. I also want to let anyone reading this know that my original gear set up was a 3.08 with a .030 pinion shim and .007 backlash. Contrary to what the Ford Racing instructions said, my 3.55 gears had the correct pattern with a .045 pinion shim and the backlash set at .010. Lastly always get new bearings!
