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

      Application. This Ford Racing Ring and Pinion Gear set will fit all 1994 to 1998 V8 Mustangs including the GT 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.

        Great investment

        This gear really is a great addition to help your 0-60 times and really boost that low end torque. Great buy.

        Should be everyones first mod!

        This was awesome! Before, my car had the stock 2.73 gears and was super slow. Now with the Ford Racing 3.55 gears my car hauls!!! I love these gears. Perfect if you daily drive your 'stang but want to whoop up on people every once in a while.
