What is the rear axle ratio of a 2002 Chevy silverado 1500 Extended Cab 4.8L V8?

The rear axle ratio for a 2002 Chevy Silverado 1500 Extended Cab 4.8L V8 is not a single, definitive answer. It varied depending on the options selected when the truck was ordered. Common ratios included 3.73, 4.10, and possibly others depending on the transmission (4L60E was common) and whether it was a 2WD or 4WD model.

To find the exact ratio for a specific truck, you need to check one of the following:

* The sticker on the driver's side doorjamb: This sticker often lists the axle ratio.

* The build sheet (if available): This provides detailed specifications of the truck.

* The vehicle identification number (VIN): A dealer or online VIN decoder might be able to provide this information.

* The differential itself: The ratio is stamped on a tag on the differential housing, usually visible from underneath the truck.

Without access to one of those sources, it's impossible to state the axle ratio definitively.
