Description
Ring-a-Ding-Ding (and Pinion)! When you’re looking to ensure your 1999-2004 Ford Mustang GT is going to perform at the highest possible level, you need to use the Nitro Gear & Axle Ring Gear and Pinion Kit – 5.13 Gears. With its superior 8.80-inch steel construction and wide design, you’re going to get a high-powered addition to your Mustang’s differential immediately.
5.13 Gear Ratio. This ring and pinion set utilizes an aggressive 5.13 gear ratio, which empowers your Mustang to take its performance to the next level. It ensures the correct transfer of power to your wheels in high-performance conditions.
Durable Construction. These wheels are built from heavy-duty 8620 steel. They have been tested for superior strength and wear resistance under pressure.
Recommended Upgrade. If you are changing the gear ratio of your current ring and pinion, this kit will require you to recalibrate your vehicle’s onboard computer with a tune-up. This can be done at home if you have a tuner.
Installation. This ring and pinion kit is very difficult to install, thanks to the intricacy of disassembling your Mustang’s differential to put it in. It will take at least 4 hours to install it yourself with advanced hand tools and advanced mechanical expertise, but professional installation is highly recommended.
2-Year Warranty. This ring and pinion kit are 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.
Application. This Nitro Gear & Axle Ring Gear and Pinon Kit – 5.13 Gears is designed to fit 1999-2004 Ford Mustang GT models. Please ensure correct model and trim before purchase.
