    Performance Upgrade. A set of 4.11 Yukon Gears are a great way to improve the performance of your 2015-2020 Mustang. Ideal for both street and track applications, these 4.11 Yukon Gears will give your Mustang a kick in the pants to place your S550 into its power band much quicker for faster off the line acceleration and better performance.

    4.11 Gear Ratio. 4.11 Gears are a great choice for increasing the performance of your daily-driven Mustang. However, it should be noted that you will see a slight decrease in fuel economy when compared to your original factory installed gears. So, if want better acceleration and don't mind a modest cost increase at the pump, a set of 4.11 ratio Gears will give you the added performance you want without breaking the bank.

    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 Handheld Tuner is a quick and easy way to fix this issue.

    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.

    1 Year Manufacturer's Warranty. Yukon warrants that their products will be free from defects in material and workmanship for a period of twelve (12) months from date of the original purchase. Some exclusions may apply, please see manufacturer's warranty for details.

    Application. This 4.11 Yukon Ring and Pinion Gear set will fit all 2015-2020 Ford Mustang models equipped with an 8.8" Independent Rear Suspension (IRS). A master bearing kit is recommended by most installers, especially on high mileage vehicles.

    Application Note. These Yukon 4.11 gears are not compatible with a 3.15 ratio differential - use differential M-4204-MT or M-4204-M.

    Technical Note. Installation costs will vary, but 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.

            To high go 373

            It was too high of gear for my Roush RS 3 Mustang with automatic transmission. I switched to a 373.
