all the 250's and 350's 2wd have I beams. i have an 02 350 2wd and it has I beams. all 4x4's have the solid axle and 2wd 450's and 550's also have solid axle just like a 4x4 but without the gears and drive axles. technically you dont body drop the 99 up superdutys cause the pinch welds are just a little lower than the frame, but the radius arm mounts, tranny xmembers, and fuel tank sit a little lower than the cab or frame. thats where the work is to get a superduty to lay out.
