This kit features a set of gears with 3.31 gear ration and made to OEM specifications. Unlike lesser kits, the gears in the kit are ideal OEM replacements whether your current gears are worn or if you need to re-gear to meet new requirements.

      OE-Quality Construction. To deliver OEM performance and quality, these gears are precision-machined from high-grade materials. This ensures that they meet OEM specifications while also having a perfect fit for easier direct fit installation.

      Recommended Upgrade. Purchasing a USA Standard installation or master overhaul kit is highly recommended for easier installation.

      Professional Installation Recommended. The kit’s included gears are direct fit and help in making installation easier. However, as replacing differential gears is still a complex process, installation by a professional mechanic is recommended.

      Includes 1-Year Limited Warranty. The Ring Gear and Pinion Kit with 3.31 gear ratio is warranted against manufacturing defects. Exclusions will apply.

      Application. The USA Standard Ring Gear and Pinion Kit with 3.31 gear ratio is designed to fit 2007 to 2014 Ford Mustang GT500 models.
