2003 Ford F-250 Super Duty Overview

The 2003 Ford F-250 Super Duty was a major transition year for the lineup, as Ford introduced the new 6.0L Power Stroke diesel to replace the legendary 7.3L Power Stroke. While the 7.3L was still available early in the model year, it was phased out mid-year, making 2003 models with this engine highly sought after today.

Additionally, refinements to the interior and new features made the 2003 model more comfortable while maintaining its heavy-duty work capabilities.

Note: King Ranch and Platinum trims were still NOT available in 2003.

The 6.0L Power Stroke was more powerful than the outgoing 7.3L Diesel, but early models had reliability issues. The 7.3L Diesel, found in early 2003 models, remains highly desirable for its durability.
