At least it is truth in advertising.

I can't recall I do have it favorited on this computer (my work computer) or my home desktop or my laptop. I'll have to see if I can find it.
IIRC stock front springs are like 340 +/- 20 or so. Rear springs however are like 370. If I'm not mistaken, most companies (skyjacker, superlift (excluding EZ ride) are 410 and rough country is 440-450 I'm pretty sure
***EDIT
Here I found these this info in my favorites-- This is lift springs for fullsize ford bronco (believe for 79's, but would be close to the 80-96 style)
Brand-------Bracket Material thickness---Coil Spring Rate
Trailmaster--4"-----None Given----------560 lbs per inch
Rancho-----1"------N/A-----------------459 lbs per inch
Rancho-----1"-2"---N/A-----------------380 lbs per inch
Rancho-----3"-----.19"---------------- 460 lbs per incharch
Rancho-----4"-----.19"-----------------460 lbs per inch
Pro Comp---4"-----.25"-----------------475 lbs per inch

Superlift----1"-2"---N/A-----------------400 lbs per inch
Superlift----4"-----.25"-----------------445 lbs per inch

Also noted in RED is the actual spring rate so there is no confusion
You will notice 2 #'s per applications (4 for the f150, due to 1 is the supercab model) It's front, rear, front rear etc
