      Description

      Add Confidence to Your Install. The USA Standard Ring Gear and Pinion Kit features gears with 3.31 gear ratio made according to OEM specifications. This ensures that the gears deliver quality, performance, and reliability that match the Mustang’s stock parts. Furthermore, with USA Standard’s high product quality standards, these are gears that you can trust.

      Triple Alloy Steel Construction. The ring and pinion gears are CNC-machined from high-grade materials in order to ensure quality and performance. Moreover, the precision manufacturing makes these gears direct fit which helps to make installation easier.

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

      Professional Installation Recommended. Re-gearing the differential is a complex process. And while the kit’s gears are a direct fit, installation by a professional mechanic is still recommended.

      Backed by 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 1986 to 1993 Ford Mustang GT models.
