Post a picture of the part number tag on the springs. @shermanator2 knows the springs, maybe he can help.
I’m guessing you got the part number from this thread:

The real story on Tremor springs
My F350 is a non-Tremor 7.3L with the Camper Package, and while the stock rake was less than non-Camper Package versions, it was still too much for me (~2.5"). I did replace my stock shocks with Fox 2.0 adjustables (0-1.5" lift) and verified during install that I picked up the additional travel...

Welcome to the club, buddy! Don’t panic and let your front end sag just yet.
You actually scored exactly what you needed. That “ATA” part number (LC3C-5310-ATA) is 100% a Tremor-specific 5,200 lb spring. The standard non-Tremor 5,200 lb springs are stamped “AMA” (the LAM door code). Whoever wrote up your paperwork was probably a little confused—or they just didn't know what they were handling. If the physical tag on that coil says ATA, you are golden, and it will keep your factory Tremor stance exactly where it should be.
Going from the 4,800 lb springs (which are usually the AVA code on our 7.3s) up to the 5,200 lb ATA springs is the perfect upgrade for plow duty. Since the ATA is technically the 6.7 diesel Tremor spring, it’s got the extra beef to handle the heavy tool hanging off your front end. It'll ride a bit stiffer when you're unloaded, but you want that extra stiffness so you aren't completely bottoming out when you're pushing snow. Pairing them with those Sumo bump stops is a solid, zero-compromise move.
Good luck and keep us posted!
