Description
Performance Upgrade. If your 2015-2025 S550 Mustang is only driven a quarter mile at a time, it's a good bet that a set of Yukon 4.88 Ring and Pinion Gears will probably be a future mod. Perfect for the serious drag racer who is looking to increase low end torque for quicker off the line acceleration and faster ET's, these 4.88 Gears feature a much steeper ratio than your original factory installed gears.
4.88 Gear Ratio. 4.88 Ring and Pinion Gears are a great choice for the 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. While in theory 4.88 gears could be used on the street, they are really intended for serious drag race applications.
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 4.88 Yukon Ring and Pinion Gear set will fit all 2015-2025 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 4.88 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.
