Bronco Frame , Engine, driveline transmission etc, but not the rearend. (It’s a trussed race rear end) All electronics Including stock Ecu tune, no pumped up turbo, she runs on 91 octane pump gas, Steering, shoot even the shifter, most the suspension but not shocks, stock ball joints, bronco frame. Last year the cooling system was stock in the stock location and that was a problem. Still stock cooling but it’s moved to the back up in the wind like on a trophy truck. As long as you don’t race 1000 miles on the pipe you’re stock rig should be epic.
I’m a nimrod so don‘t take my comments as fact. Ford made a big deal out of being as much stock as possible.
You‘re mileage may vary, odds computed on day of drawing, everything subject to change.
You could totally build one identically with off the shelf ford parts, a cage, aftermarket desert rear end and Fox Shocks. Ford did put some money into the custom body with 1 off molds so that part might be tough but you could do it.
Where did you get your info from? I think you may have not looked very closely at it. Can’t be built with off the shelf parts from Ford. Unless they made big changes in the frame from when Gieser Bros built this one to the one that is being released then you can’t even get the frame under the stock bronco. Never mind I found the answer. It’s a f150 frame.
