Ford F-450 Super Duty

The heavy-half of the Super Duty chassis cab, built to carry a workload all day.

The F-450 chassis cab shares its dual-rear-wheel frame and Dana axles with the F-550, but pairs them with a tighter wheel cut for a class-leading turning radius in tow-truck and service-body builds.
