Convert 2 wheel to 4wheel

Love this truck! only has 120,000 on it and it runs like a dream. Love the 7.3 L power stroke and really don't want to sell it. Just was wondering and checking out my options. I have had it for 11 years

Yes but it does Take a bit of work and possibly some fabrication a good place to start would be figuring out what gear ratio you currently have in your rear end and seeing if you will have to change it to get it to match the front differential that your going to be using or decide on getting a match set of both front and rear axle sets and maybe go better than stock the last time I built a 4x4 I went with 5ton Rockwell axles front and back with 4 wheel steering and full hydro steering also you need to make the determination of what transfer case your going to be using for your conversion
