FORD F-450 SD MODIFICATIONThe Super Duty trucks are larger, heavier built commercial/industrial series pickup trucks with heavier-duty body-on-frame  steel ladder frames, axles, springs, brakes, transmissions, more  powerful engines, and all other heavier/bigger components (with much  higher payload and towing capacities) than the older traditional  equivalent F-250, F-250HD (Heavy Duty), and F-350 Ford truck lines. The  two-wheel drive and four-wheel drive model frames are the same in the  F-250 and F-350 series, making conversion from a two-wheel drive model  to a four-wheel drive model less difficult than in other truck models.  This is because the '99 model year of the F-series has all the bolt  holes in the frame for both two-wheel and four-wheel drive precut by the  manufacturer.
