Suspension (mostly rear) and tires are pretty much it, plus the option to have a dual tire rear axle. The basic chassis, engine, tranny, steering, etc. are identical in similar models. The 350 will also have the cab-mounted marker lights required by its higher GVWR rating. However, some 250's may have those as well if it has extra payload or other options that increase the GVWR above the 8600 lb limit.To me the only difference between a 250 and 350 is the suspension. Am I totally wrong with that?
UPDATE: The divider between truck class 2 & class 3 is now at 10,000 lbs, not 8600 as I mentioned above.
