What is my gear ratio?
Make sure to verify gear ratio by using one of the following methods.

1. Divide the number of teeth on the ring gear by the number of teeth on the pinion gear.

2. Verify ratio through dealer with your VIN number.

3. You can determine the originally equipped gear ratio on a GM vehicle by identifying the appropriate RPO Code on your GM Service Parts Identification Label. This label is typically found on a sticker attached to the inside of the glovebox door, or in the center console, or in rare cases in the trunk. The RPO Code related to gear ratios will start with "F","G" or "H".
