To tell what gear ratio your Chevy Truck has you can find out the gear ratio by looking for the RPO Codes.

The RPO codes can let you know what gear ratio your Chevy Truck has.

On a Chevy Truck the RPO codes are usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.

Also a list of gear rations for Chevy Trucks are as follows.
