Ok, I've just been searching here for spring s codes that match these part #'s for front springs.
F81AADD and #RPN1128 was stamped under the other #.
I am hoping these are snow plow prep springs x codes or similar, as they came froma 1999 F250 XL 4x4 work truck with 6spd and v10 and plow.
I have done sesarches read tons of threads in the searchs for front springs, spring codes, part # etc etc. I also have a 2 vol set of the 2000 ford superduty work shop manual and I can't find different spring part #s in the manual either. The door sticker was removed on this truck in the junk yard..so the sticker is no help. I have the Vin #1FTNF21S5XEA96298
Truck had 79k on it
Here are pictures.
