Does this truck still have its door jamb VIN sticker in place? That sticker should have the spring codes listed on it under the SPR heading.

I’ll have to check that when I get home doubt it will because it’s a rot fest in that thing but who knows

I believe it said XB is that the heaviest duty springs the 99-04 super duty could come with?

so what's the rating for them? the b spring from what i can find seems to be rated for ~3000 pounds and the x spring is rated for ~2630 pounds is that right? or are there multiple variations of it with different ratings like the rear- one i see with the number 43-1261 has a rating of 3000 for the 99-04 where as there's another one numbered 43-1263 with a rating of 3300 which is the OEM rating then? just making sure i wanna learn this kind of stuff lol part numbers too maybe
front has 2 leaf's rear has 5 total with a 6th one that just- rests on top not part of the shackle a helper thing maybe?

Edit: nvm i think i figured it out but still be free to addon to this

The X codes (6000 lb rating for the pair) were a factory option when the snow plow prep was selected. They are a 2 leaf pack.
I don’t currently have info on the rear B codes.

so regardless of cab type and bed length as long as the snow prep was selected they all had x codes

curious to hear about the b code ones if you do manage to find something
