    Improve Performance. Get your classic 5-liter Fox Body Mustang up and moving with a set of Yukon 4.56 Ring and Pinion Gears. Featuring a much steeper ratio than your original factory installed gears these 4.56 Yukon Gears are ideally suited for drag racers who are looking to increase low end torque for faster off the line acceleration and quicker elapsed times.

    4.56 Gear Ratio. 4.56 Ring and Pinion Gears are a great choice for those who are looking for faster acceleration and quicker 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. While 4.56 gears can be used on the street they are really intended for drag race applications.

    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 new Speedometer Gear is an inexpensive way to fix this issue.

    Application. This 4.56 Yukon Ring and Pinion Gear set will fit all 1979 to 1985 V8 Ford Mustangs equipped with a 7.5" 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.
