Rear blocks are 4" in the F350 SRW, 2" in the F250. GVWR for F350 SRW is 9900 in most states and the F250 8800 in most states.

Besides the other things mentioned. The early to at least mid 90s trucks had different type front axles. The 250 had independent front suspension while the 350 had the straight/solid axle.

The current production model f350 has one heavier spring upgrade. Depsite the option to select the "heaviest spring" it is not the same for the f250 and f350. This is where the "computer selected spring" stuff comes into play. The F350 does site higher and that has to do with the spring and the blocks.

To the best of my knowledge, this info re: springs is incorrect. What are you basing this statement on?
