    Description

    Performance Improvement. Installing a set of 3.73 SR Performance Gears will definitely wake up the performance of your V6-powered 2011-2014 Mustang. Ideal for both street and track applications, these SR Performance Gears will place your V6 Pony into its power band much quicker for faster off the line acceleration and more low end grunt.

    3.73 Gear Ratio. 3.73 gears are a great combination of performance and fuel economy that are ideal for a daily-driven Mustangs that see a lot of highway time. If you put a lot of miles on your Pony and don't want to increase your cost at the pump, a 3.73 ratio will still give you the added acceleration you want without dramatically compromising fuel economy.

    Quality Construction. SR Performance manufactures their ring and pinion gears from forged 8620 triple alloy steel for superior strength. Featuring CNC cut and lapped gear teeth, SR Performance completes their gears in a black oxide finish for long lasting corrosion resistance.

    Recommended Upgrade. Changing the rear axle gear ratio will throw off the calibration of your Mustangs speedometer, but a Handheld Tuner is a quick and easy way to fix this issue.

    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.

    Professional Installation Recommended. The installation of Ring and Pinon Gears can be a very intricate process, so mechanical experience is highly recommended. Follow the included instructions for best results.

    Application. This 3.73 SR Performance Ring and Pinion Gear set will fit all 2011-2014 V6 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.
