    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 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.

            Great Gears

            These 3.31 gears were perfect for my daily driver which had the stock 2.73 gears (manual transmission). I could definitely feel the acceleration difference in the lower gears that I was hoping for, but the rpms stayed lower at higher speeds (2200rpm @75mph). I highly recommend this gear ratio. Thanks AM!

            Ford Racing Gears

            I have been buying and using Ford Racing Gears for 15 years with great results! Excellent price, excellent quality, and the 3.31 gear was perfect for my street/strip 92 turbo coupe! As always thanks to American Muscle for stocking quality parts and for providing fast shipping!
