    Features & Details

    • Ford Racing Quality
    • Strong Forged Construction
    • 3.55 Gear Ratio
    • 8.8" Ring Gear Diameter
    • For Street or Track Use
    • Fits 2007-2014 GT500 Mustangs
    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 GT500. 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.

    Application. This Ford Racing Ring and Pinion Gear set will fit 2007-2014 Shelby GT500 Mustangs. A master bearing kit is recommended by most installers, especially on high mileage vehicles, see drop down option above.

    Attention 2010 and newer Mustang Owners. Starting in 2010 Ford changed the inner rear gear pinion bearing in all 8.8" equipped Mustangs. Because of this you will require a new 8.8" rear gear pinion bearing (Ford part# 9L3Z-4630-A) for proper installation, please 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.

      Finally a quiet ride

      I bought 3.73s a few years ago. They were extremely loud and got louder as time went on. I couldn’t stand it anymore so I decided to go with this set up. Got the car back yesterday and it doesn’t even make a sound. Soooo quiet finally. The torque feels pretty much the same so I really didn’t lose much. I did this along with an Eaton LSD and a complete bearing package. I couldn’t be happier.
