Ford Racing 2015 Mustang GT 8.8-inch Ring and Pinion Set - 3.55 Ratio

If you're looking to change up the gearing in your 2015-2025 Ford Mustang GT for competition use, this Ford Racing 8.8-inch ring and pinion set with a 3.55 ratio is a solid option. Swapping your gear ratio can significantly alter how your car accelerates and how it performs at higher speeds. A 3.55 ratio generally offers a good balance, providing improved acceleration over stock without sacrificing too much highway drivability, though this set is intended for off-road competition only.

This set includes the ring gear and pinion, an OEM crush sleeve, and a pinion nut, all finished in a black oxide coating to help resist corrosion. Ford Racing is known for making well-built drivetrain components, and these gears are designed to handle the demands of performance driving. Keep in mind that installing a different gear ratio will require recalibration of your speedometer and other vehicle systems, and this set is specifically designed for use with the Super 8.8-inch Independent Rear Suspension center section.

For installation, you'll need the M-4210-B3 install kit, which includes necessary bearings and seals. Remember, this part is intended for competition use only and should not be installed on vehicles driven on public roads and highways, as it may violate emissions laws.
