ive read quite a few posts here, and with the 2017 and newer seems like the only difference between the two models is the badge, weight limits , and extra leaf spring . Can anyone confirm my observations or add to this?What package does the sway bar come with on each model? Thanks

 

And axles now.

 

I am going to add in rate of taxation. I don't know how or if it applies where you are but it can be a factor. Where I am there is luxury tax on 250's but not on a 350's as a result not to many new 250's on the lot. That and the fact my payload can be fairly high meant I didn't spend a lot of time researching 250's

 

The rear sway bar comes with the Camper Package. On my F-350 that forced the 18" tires and I believe it allowed or forced the 3.55 axle ratio. I was try to get the 3.55 axle ratio and I had no objection the Camper Package to get there because I also wanted the rear sway bar.

 

The sway bar is part of the Camper prep package.

 

Depends on gas vs diesel. Axles in gas 250 and 350 are same, transmission is different in gassers.

 

Starting with base (XL trim) models with standard 6.2 gas engines and no options, there are some key mechanical differences:

• The 250 gets the 6R100 automatic transmission, three-leaf rear spring packs, and a 650 CCA (Group 72) battery
• The 350 gets the 6R140 automatic transmission, four-leaf rear spring packs, and a 750 CCA (Group 75) battery

Adding options can dramatically change the final configuration. For example, adding the 6.7 diesel option to the 250 changes the AT from the 6R100 to the 6R140, but it still gets the Ford Sterling rear axle. Adding the the 6.7 option to the 350 changes the rear axle from the Sterling to the Dana. Adding the optional HD tow package to the diesel-equipped 250 also changes the rear axle from the Sterling to the Dana.

The optional Camper- and Snowplow/Camper Packages add the rear sway bar to the single rear wheel trucks, but these options are not available on the certain trucks with 20" wheels and/or higher trim levels. And, regardless of option selections, the four-leaf rear spring packs are the limit on a 250, and five-leaf packs are the limit on the 350 SRW.

And 350 is only about $1500 more than a 250, with a higher payload.

 

the attached file details the differences, 6r140, more rear leafs, sure helped me decide.
