No...depending on what make model and year, normally the axles are different length...

Also different wheel studs, sometimes different brake drums...

Normally if you change the studs out to accept duals, you will find your outside dual sticking out further than on a 'real' dually...

Check the axle part numbers for your truck and then a dually in the same year, see if they are the same?

there have been variations in the 14 bolt. If the perch width is the same as your truck, you should be good. Also keep in mind chevy spring perches are actually an inch closer (IIRC) on the back than the front. Just measure perch to perch, if they are the same, it will work. Then you should just need wheels, fenders, and a box (maybe?) to run duals.

Also the fronts are different, as you probably know, if you want to run dually front wheels.
