1983 Chevy S-10 Tahoe rear axle gear ratio?

The rear axle gear ratio in a 1983 Chevy S-10 Tahoe wasn't standardized. It varied depending on the engine, transmission, and options chosen when the truck was ordered. To know the ratio of a specific truck, you'd need to:

* Check the vehicle's documentation: The owner's manual or a build sheet (if available) might list the axle ratio.

* Look for a tag on the differential: The differential housing usually has a tag indicating the gear ratio. You'll likely need to get under the truck to see it.

* Use the VIN: With the VIN, a dealer or online service might be able to access the original build information, including the axle ratio.

There's no single answer to your question. Common ratios for that era might have included 3.08, 3.23, 3.42, and 3.73, but your truck could have a different one.
