What is the gear ratio of a 2005 Chevy Tahoe?

The gear ratio of a 2005 Chevy Tahoe varies depending on the specific transmission and axle ratio selected by the manufacturer (and thus, the trim level and options). There's no single answer.

To find the gear ratio for *your* specific 2005 Chevy Tahoe, you need to:

1. Check the sticker on the driver's side doorjamb: This sticker often lists the axle ratio (e.g., 3.73, 4.10). This is the final drive ratio in the rear differential.

2. Consult your owner's manual: The owner's manual should specify the gear ratios for your transmission (automatic or manual). This will list the ratios for each gear.

3. Look at the RPO codes: The RPO codes (Regular Production Option codes) on the sticker on the driver's side doorjamb or glove box can help you identify the specific transmission and axle ratio used in your vehicle. You can then cross-reference those codes with GM's documentation (possibly found online or through a GM dealer) to determine the exact gear ratios.

Without this information, it's impossible to give you a definitive answer.
