    Improve Performance. Installing a set of 3.73 Yukon Gears will get your V6-powered Mustang up and moving faster. Steeper rear Gears will place your 1999-2004 Mustang into its power band much quicker for faster off the line acceleration. These 3.73 Yukon Gears are ideal for both street and track applications.

    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. 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 3.73 Yukon Ring and Pinion Gear set will fit all 1999 to 2004 V6 Ford Mustangs equipped with a 7.5" 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.

      loud

      I had a local shop install and after break in the gears were to loud. I had the same shop reinspect their setup. They say it is to spec. I took it to another shop they also said it was to shimmed correctly. I am told it is the cut of the gear which is making them loud. I am now looking for new gears elsewhere.
