Improve Performance. Are you looking to improve the performance of your V8 powered New Edge Mustang at the track? If so, you may want to consider a set of Yukon 5.13 Ring and Pinion Gears. With a much steeper ratio than the original factory installed 3.27 gears, these Yukon 5.13 Gears are the perfect upgrade for serious drag racers that are on a quest for faster off the line acceleration and quicker elapsed times.

5.13 Gear Ratio. 5.13 Ring and Pinion Gears are a great choice for the 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. While in theory 5.13 gears could be used on the street, they are really intended for serious 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 Ford Racing Speedometer Recalibration Tool is an inexpensive way to fix this issue.

Application. This 5.13 Yukon Ring and Pinion Gear set will fit all 1999 to 2004 GT Ford 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.
