81250 is the correct Moog part number to replace the OEM front spring.
Got these installed this weekend with new oem struts from rock auto. The truck rides/drives different. Almost like the spring is too stiff or something? Hard to explain. When hitting a dip or bump that's not sudden, it rides fine. If there's a sudden drop in the pavement, it feels very harsh. In other areas, it feels "unsettled" if that makes since. Like the strut and spring aren't pairing well with each other

Have you experienced any of that?

I only replaced them because the shocks were at 180k and felt stiff (worn out) and the springs had 300k miles. Sadly, it's only marginally better than before. For comparison, my dad's 2012 rides very similar to my 19 Denali. This does not compare

Wondering if there's anything I can check or do to resolve this. I considered putting the 100k mile oem springs off my Yukon, or even going back to my original 300k miles springs.
