Been searching for the difference between the F150 7700 and the Standard F150 model.

Aside from beefier torsion bars, axles, brakes, wheel bearings, and springs, there seems to be some debate with regards to whether or not the frame is thicker or has more bracing when compared to the Regular F150.

Does anyone know for sure exactly what the differences were and if the frame was for sure one of them?

----------------

I have a 7700 frame and axles with a bad cab at my disposal.

My main driver is a 99 F150 with a failing rear axle. I might just swap the axles.. but if the 7700 has a thicker frame I might just opt to do a cab and box swap.

Thanks!
