Nitro Gear & Axle Ring and Pinion Gear Kit; 4.11 Gear Ratio (05-10 GT)

The Best Ring and Pinion. When you’re looking for improved performance and economy for your 2005-2010 Ford Mustang GT, then you need the Nitro Gear & Axle Ring Gear and Pinion Kit – 4.11 Gears. Its heavy-duty construction and big gear ratio provide you with the acceleration you desire to improve your track times while not overworking your engine.

Heavy-Duty Steel. This kit is forged from superior 8620 steel, which provides lasting wear and tear resistance. It will keep the strength of your differential in peak condition for years to come.

Recommended Upgrade. If your Mustang’s gear ratio was not 4.11 before installing this kit, you will need to have your computer re-tuned to ensure speedometer accuracy. If you have a handheld tuner, it can be done with that, or you can have it done professionally.

Installation. This is a very mechanically-advanced kit to install, so expertise, specialized tools, and either a car lift or jack stands will be needed. Please allow at least 4 hours for installation, but professional installation is highly recommended in this case.

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.

Application. This Nitro Gear & Axle Ring Gear and Pinon Kit – 4.11 Gears is designed to fit 2005-2010 Ford Mustang GT models. Please ensure correct model and trim before purchase.
