F250 springs are arced downward and have a HIGHER spring rate than the F350 by around 1200lbs
YES the F250 has a HIGHER rate spring. It is due to the PIS POOR Design flaw of the TTB and how it makes the leaf spring flex in ways they were never designed to

When I converted my F250 to the Dana 60 front end, I went to a local leaf spring shop in Baltimore called Middleton and Mead, they showed me the catalog that had the different available springs, there was no distinction between small block, big block/diesel or cab and chassis. The aftermarket springs were divided up between F250 and F350 with each category having 4 different springs available, all depending on the spring rate that you needed. The different springs had a different number of leaves in the pack.
I ended using a 2 ply F350 spring then having them de-arched about 1.5" so that the truck wouldn't be jacked up in the sky, they matched very well to the new rear springs I installed a year earlier.
Do yourself a favor and call a reputable spring shop and talk with someone who knows what they are doing instead of being mis-led by the interweb know-it-alls that seem to lurk on this site.
here's a link that has some decent listings for front leaf springs.

Ford didnt just put a different spring code on the door jam sticker for the hell of it. They all have different weight ratings. As for the 2 or 3 leaf deal. EVERY f250 and F350 left the factory with only 2 leafs. The aftermarket came up with the 3 leaf deal for the extra weigh of plows and winch bumpers.
I have been working on these trucks for over 20 years, I am NOT an internet know it all. The level of my craftsmanship and the NUMEROUS truck I have built should more than attest to that
