If you are wondering just what it would take for this dually conversion, it's as simple as a dually adapter conversion kit.
These dually wheel adapters are precision adapters that let you run 19.5 dually wheels on your one ton dually truck.
They bolt directly to the one ton axle wheel 8 lugs and have 10 wheel studs to which you can mount a 19.5 wheels.
They also act like spacers between the dually tires so you won't have problems with the larger dually tires touching. Touching tires are very dangerous and under load will almost certainly cause tire failure.
These adapters such as the ones made by Arrowcraft are made from steel not aluminum. They are simple to install, just as easy as changing a dually tire.
Arrowcraft and other manufacturers designed the adapters to mount directly to your existing axle stud requiring no modifications on your part. You can buy the adapter by itself and use your own wheels.
One thing to remember, these adapters do not increase load capacity. Depending on dually rim and dually tire width, choose one inch, 1.5 inch, 2 inch and 3 inch dually adapters.
