Improve Off The Line Acceleration.
Are you on a quest to improve the low end grunt and performance of your 2011-2014 V6 Mustang? If you answered yes, you should consider upgrading to a set of Richmond Excel 3.73 Ring and Pinion Gears. From the factory most 3.7L V6 Mustangs were equipped with either 2.73 or 3.31 gears, which work very well to conserve fuel mileage, but leave something to be desired when it comes to performance. Richmond's Excel 3.73 Gears have a steeper ratio, when compared to the stock gears, which will place your Mustang into its power band much sooner for a noticeable improvement in torque and off the line acceleration. A set of 3.73 gears are perfect for use in street, track and drag applications.Superior Quality.

Using state-of-the-art manufacturing processes and extensive quality control testing, Richmond produces a superior quality Ring and Pinion Gear Set at an excellent price. Richmond is so confident in the quality of their products that they back them with a 6 month, 50,000 mile no-nonsense warranty.Required Upgrade.
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. Recommended Upgrade.
Please note that when changing the gear ratio of your Mustangs rear differential that the calibration of your speedometer will no longer be correct and will display the wrong speed. However, you can easily fix this annoying issue with a Handheld Tuner
This 3.73 ratio Richmond Excel Ring and Pinion Gear set will fit all 2011 to 2014 3.7L V6 Mustang models equipped with an 8.8" solid axle 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.
