    Improve Performance. Are you looking to add big bite to your 2005-2009 V8 powered Mustang? If so, you may want to consider upgrading to a set of 5.71 Yukon Ring and Pinion Gears. Featuring a much steeper ratio than your original factory installed gears these 5.71 Yukon Gears are ideally suited for the serious drag racer who is looking to increase low end torque for quicker off the line acceleration and faster elapsed times.

    5.71 Gear Ratio. 5.71 Ratio Gears are the perfect choice for the serious drag racer who is looking for quicker acceleration and faster 60 foot times. However, it should be noted that you will see a noticeable decrease in fuel economy when compared to your original factory installed gears. 5.71 Ring and Pinion Gears are really intended for serious drag race applications and should not be used on street vehicles.

    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 5.71 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.

      Nice product.

      Very interesting! The gear switches are quick and efficient! Better comparison than original stock gears.
