    Improve Performance. A set of 4.30 Yukon Ring and Pinion Gears will give your 4.6L GT Mustang a much needed kick in the pants. A steeper set of rear Gears will place your S197 GT into its power band much quicker for faster off the line acceleration and a noticeable increase in low end grunt. These 4.30 Gears are a great choice for both street and track applications.

    4.30 Gear Ratio. 4.30 Ring and Pinion Gears are a great choice for increasing the performance of your Mustang. However, it should be noted that you will see a decrease in fuel economy when compared to your original factory installed gears. So, if you want better acceleration and don't mind a slight increase at the pump, a set of 4.30 ratio Gears will give you the added performance you want without breaking the bank.

    Quality Construction. Made from incredibly durable forged 8620 triple alloy steel for superior strength, Yukon backs their Ring and Pinion with a 1-year limited warranty. Yukon also takes full advantage of the most up to date state of the art technology in their design and manufacturing process. No matter how you look at it, this gear set is built to last.

    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 4.30 Yukon Ring and Pinion Gear set will fit all 2005 to 2009 GT and Bullitt Mustangs equipped with a 8.8" rear end. 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.
