Ah, the great axle debate: Most believe that prior to the 2011 models, there was no difference between an F-250 & F-350 SRW axles. Some believe that starting in 2011 in order to keep up with the increasing capacity wars, Ford upgraded the internals of the SRW axle for F-350s. Others believe that Ford is lying when they publish these specs for the F-350. At any rate, Ford is working very hard at propagating the lie since it is now in 5 years running of specs.
Back in the 90s one could spec either a 2” or 4” block between the axle and springs for either a 250 or 350. Somewhere along the line the 2” became the standard for the F-250 and the 4” became the standard for the F-350. Because the 2” block sets the 2011 - 2015 trucks almost level, they look very rear end droopy with the least little bit of load. Ford has a service bulletin out advising to change the blocks from 2” to 4” to fix the droopy problem.
On axle ratios, if looking at new trucks, for Ford, they will pick the ratio based on what you pick for options. With the 6 speed rear end ratio matters very little. With the two OD gears (similar to the competition) it gets the best possible highway mileage.
