Ford lists a rear axle rating of 6290lbs and MAX GVWR of 10K for an F250. The F350 SRW has a rear axle rating of 7190lbs and a GVWR of 10K-11.5K.
Actually Fleet Fords body builders specs shows four different RAWR for the F350 SRW 6.2/6.7 line.
1. 6290 RAWR gas and diesel
2. 6730 RAWR gas and diesel
3. 7000 RAWR gas and diesel
4. and one 7180 RAWR for the 6.2 gas reg cab 4x4 truck only.
The F250 has one 6290 RAWR for the reg cab 2wd gas truck only.
All other F250 gas and diesel configurations come with the 6100 RAWR.

The F250 heavy service package uprates the the trucks suspension to the same specs as the F350 SRW truck.
Th point here, as my other reply, was if moving up to a F350 SRW watch which GVWR package the truck is plated at .....if the trucks GVWR is important to you.
While I agree people need to pay attention to what the trucks are rated at I believe you are confusing the spring rating with the rating of the axle. The link you provide lists only two AXLE ratings,
F250 - 6200lbs
F350 - 7200lbs
While the numbers you quote are what I see listed for the spring packs.
So no matter what spring package gets selected on an F250, it's rear axle isn't as strong as the F350's with the same spring rating.
the ratings are based on the tires
If you want a HD F250 get the 18 in tires
Ford makes it confusing on the F250 because with 3 different spring packs and 2 different tire ratings the GVW stays the same at 10000lb
