    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 new Speedometer Gear is an inexpensive way to fix this issue.

    Application. This Ford Racing Ring and Pinion Gear set will fit all 1986 to 1993 V8 Mustangs including the GT, 5.0 LX and Cobra models. 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.

      Hard to beat Ford Racing

      I installed these myself, first time ever doing gears. Did a lot of research and took my time. The gears looked great right out of the box. I installed these along with a Torsen T2R with no issues. I'm still in the break-in period and taking it easy but so far all seems well.

      New style Ford Diff Gears

      New 3.55 Ford gears fit perfectly. Please know that these gears are "hobbed" rather than "milled" which makes them stronger but requires different setup than older/aftermarket gear sets. Ran warm the first few miles, don't forget to break them in.
