Big 4x4 Truck

My current Big 4x4 Truck project is making a custom Ford Explorer Sport Trac fully modified for 38 inch tires. In these pages you can follow along and see all the details as they are thought out and put into action.
Lots of wallpaper sized pictures of the 4x4 project Ford Explorer Sport Trac in action.
Before

A stock Ford Explorer Sport Trac is pretty good on the highway in USA, but can it be customized in a way to get it into the rough Icelandic snow and ice driving?
The plan is to make this into a true off road custom Ford Explorer Sport Trac. Starting with the insertion of a Dana 44 whole front axle with disk brake kit in front, but use the Ford 8.8 rear axle in the rear. Both axles to be fitted with air-lockers and 4.88 gear ratios. Four link suspension in the rear and old Bronco suspension in front - except for the airbags that are to be used both front and rear.
