What is the width of a dually axle from flange to flange on a '01-'08 Chevy? Is is the same width as a single wheeled truck axle? Thanks for any help.

The dually axle is wider.

There used to be a guy on here, his name was NODMAX I think and he had a DRW truck that he converted to an SRW truck. As far as I knew, his next plans were to put a 2500HD axle in because the DRW one was too wide. He ended up just putting 2" wheel spacers on the front wheels to make the truck look even.

A dually axle is going to be 4 inches wider.
