If you're serious about performance, you’ll want to check out the Ford Racing ring and pinion sets. These bad boys are built with a focus on getting the most out of your ride. Each set is rigorously engineered and tested to ensure they can handle the demands of high-performance driving. The black oxide finish isn’t just for looks; it adds a layer of corrosion resistance that keeps these gears in top shape, even when the weather doesn’t cooperate.

Now, let’s talk ratios. You’ve got options, and whether you’re looking to hit the track or just want to enhance your street performance, there’s a ratio that’ll fit your needs. Just a heads-up: if you’re considering the 3.15 ratio, it won’t work with the 3.31, 3.55, 3.73, or 4.09 gears. Make sure to pair it with the right differential, like the M-4204-MT or M-4204-M, to keep everything running smoothly.

This gear set is designed for competition use, so if you’re planning to hit the public roads, you might want to think twice. Installing these on a street-driven vehicle could lead to some legal headaches in the U.S. and Canada, especially regarding emissions regulations. Stick to the track where they belong, and you’ll be just fine.

Included in the set is a 3.73 ratio ring and pinion, along with an OEM crush sleeve and pinion nut. It’s specifically made for the Super 8.8 in. Independent Rear Suspension Center Section, which means you’re getting a tailored fit for your Mustang.
