    Upgrade OEM Gears. Are you looking to upgrade to a stronger set of rear gears? Then look no further than installing a set of genuine Ford Racing Gears in your Pony. Ford Racing Ring and Pinion Gears are perfect for street, road, and race applications.

    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 1999 to 2004 4.6L V8 Mustangs including the GT, Bullitt and Mach 1 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.

        is my 2003 gt 8.8 inch??

        • The 2003 GT model Mustangs came factory with a 8.8in rear end with 3.27 gears. As long as your rear end drivetrain has remained stock, that is the size that you have in your Mustang.

            Great!!

            Ford Racing products are definitely reliable, and these babies are no exception! No problem installing! I was sick of the 4:10 gears my Stang came with, so I went a little milder, but they're a great compromise for mileage and jumping off the line. Thanks American Muscle!
