Although our old F-250 super duty is a massive truck, we are going to trim it down and make it function like a trail rig should. Until its transformation is complete, the truck is fittingly called the Stupid Duty! The current front suspension has very limited upward and downward travel. It's like rockcrawling with a tractor. The 7.3L Power Stroke turbo diesel engine, factory 4R100 automatic transmission, and NV273 transfer case have recently been overhauled and are in perfect working order, so they will be left alone. Why fix what ain't broke?
