Improve Performance. Does your 2010-2014 GT Mustang live its life running a quarter mile at a time? If so, you may want to consider upgrading to a set of 5.71 Yukon 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.

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.

Application. This 5.71 Yukon Ring and Pinion Gear set will fit all 2010 to 2014 GT and Boss 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.
