Is F-450 wider than F350?
Yes. In typical configurations, the F-450 is wider than the F-350, primarily due to its dual rear wheels and broader rear track. Exact measurements vary by year, cab/bed setup, and whether mirrors are extended, so consult the specific Ford spec sheet for precise numbers.
Understanding truck width and why it matters
Width on a pickup is not a single number. Different measurements are used in specs: overall width (excluding mirrors), width with mirrors, track width (distance between the centers of the wheels on an axle), and body width. For everyday driving, the external width including mirrors affects garage clearance and lane positioning; for handling and load stability, track width and body width are more relevant.
The following list explains the factors that influence the published width numbers for Ford Super Duty models.
- Body design and axle configuration: The F-450 DRW uses a wider rear axle and often wider fender flares to accommodate dual rear wheels, which increases overall width compared to the F-350 SRW.
- Cab and bed combinations: Crew Cab, SuperCab, and bed length can subtly affect width measurements once mirrored panels and trim are included in the spec.
- Mirror options: Standard versus extended/towing mirrors can add significant width when measured with mirrors included.
In summary, width is influenced by several components, but the main factor distinguishing the F-450 from the F-350 is the dual rear-wheel setup on the F-450 and the associated fender/wheel track design.
Official spec comparisons (year-specific)
Ford publishes width specifications that vary by year and by whether the model is SRW (single rear wheel) or DRW (dual rear wheel). The F-450 is generally wider than the F-350 SRW, and the gap is more pronounced when you compare DRW models, as both F-350 DRW and F-450 DRW use wider rear assemblies but the F-450’s wider frame and additional hardware push the width higher. For precise measurements for a given configuration (cab style, bed length, and mirror option), consult Ford's official product sheets for that model year.
Common width references you may encounter
Note that numbers vary by year; the ranges below illustrate typical ordering rather than exact inches. Always verify the current spec sheet for your exact configuration.
- F-350 SRW overall width: generally around 80–81 inches (body width) excluding mirrors; with mirrors, roughly mid-90s inches depending on mirror type.
- F-350 DRW overall width: slightly wider than SRW due to DRW width; can approach 90–95 inches with mirrors depending on configuration.
- F-450 DRW overall width: widest in the lineup in many configurations; with mirrors and dual rear wheels, can exceed 95 inches and potentially approach or exceed 100 inches depending on year and mirrors.
Again, exact values depend on year and configuration; verify with official Ford data for accuracy.
Conclusion: Is the F-450 wider?
Yes, in most standard configurations, the Ford F-450 is wider than the F-350, driven by the dual rear wheels and wider rear track on the F-450. When comparing widths, be mindful of whether you’re measuring body width, track width, or width including mirrors, as results will differ. Always check the specific model-year spec sheet for exact numbers.
Summary
The Ford F-450 is typically wider than the F-350, especially in DRW form, due to its dual rear wheels and wider rear track. Differences can vary by year, cab/bed configuration, and mirror options. For precise figures, consult Ford’s official specifications for the exact model year and configuration you are evaluating.
