It is more than springs. The E450 has a 4.56 Dana 80 instead of 4.10's. That axle is also of a wider track width. I saw some Ford documentation as well the frame is of heavier gauge steel. All-in, it makes a 3500lb difference in GCWR besides upping the GVWR to 14,500lbs.
They have gotten closer in the last half decade. E350 track has grown, so the E450 is not only 3.5" wider (rear track width) vs the 7" difference previously.
E350 has the same 10.5" differential that the E450 used to have. The newer (2012+?) E450s now have a 10.75" rear diff. The E450 does have a heavier housing however, so it's rated ~9500 pounds vs 8500 for the E350. Brakes are now the same but the E450 brake booster does make more pressure (hydroboost vs vacuum boost). E350 has the same frame as the 14,050 GVWR E450 but the 14,500 GVWR does have a heavier frame.
GCWR is the biggest difference, with the 4.10 gears (E350 optional) rated at 18,500 pounds and 4.56 gears rated at 22,000. Note that 4.56 gears are now standard on the E350 as well starting with 2016 models. 4.56 is the only ratio on E450s.
