Differences between Ford SD F350 and F450?

I’ve been comparing the F350 to the F450. According to Ford’s “build your super duty”, a CC, 8’, DRW, 4WD F450 is about $3500 list more expensive than a like model F350. The F350 has a payload rating of 5920 and a gooseneck tow rating of 23,500. The F450 has a payload rating of 5450 and a gooseneck tow rating of 31,200. Both are rated to tow 19,000 conventionally.

The F450 has 19.5” wheels yet looses 470 lbs of payload to the F350. What’s up with this? The Ford specs are sketchy at best so what “upgrades” come with the F450 to consume 470 lbs? Heavier frame construction? Transmission cooler? Different rear axle assembly? Larger brakes? What else?

How would one source Ford technical component specs like rear axle information or brake rotor and pad area on Super Duty vehicles? Even our local dealer’s “fleet specialists” go “deer-in-headlights” when you ask for this kind of information.

  • I'd try ford-trucks.com for specs. F-450s have a few changes including a massive different rear axle and front end that turns really tight. I believe they are heavier with these changes. Mine also has different rear springs. Note: the f450 chassis cabs have higher GVWR.
  • Yup I've been researching it also and find the 350 has better payload for a TC than the 450 thus far
