Does my 2004 suburban have 4x4

That sticker does not say. Look under the truck for a front differential and driveshaft.

Take a picture of the RPO sticker to your local Chevrolet Dealer. They can tell you by looking at the option codes on the sticker. Hope that helps! Jim

IT SHOULD HAVE A BUTTON ON THE DASH FOR TRACTION CONTROL IF NOT SEE IF THERE ARE CV AXLES GOING TO THE FRONT WHEELS
