Description
Heavy-Duty Power Gears. When you’re looking to take your 1999-2004 Ford Mustang GT to a new level of performance for the track or the street, then you need the Nitro Gear & Axle Ring Gear and Pinion Kit – 4.88 Gears. The durable construction of these 8.80-inch gears provides you with performance and power that you’re not going to find anywhere else.
4.88 Gear Ratio. This ring and pinion functions on a 4.88 gear ratio, which prioritizes power and performance over fuel efficiency. This makes sure that your engine will deliver the power you need to take your Mustang over the line.

Recommended Upgrade. This ring and pinion requires you to make a tune-up if you’re changing the ratio of your Mustang’s ring and pinion. This can be done at a mechanic, or at home if you have a handheld tuner.
Installation. Ring and pinion kits have a very mechanically-advanced installation process, requiring specialized tools and advanced mechanical expertise. It will take at least 4 hours if you’re putting this in yourself, but professional installation is highly recommended.
2-Year Warranty. This ring and pinion kit is protected by Nitro’s 2-year warranty, defending against manufacturer defects from the date of purchase. See Nitro Gear’s full warranty for complete details.
