I originally used my VIN to get the parts - 84729912. They were VIN matched for the 2025. Once they arrived, the back GMC emblem was too small, same size as the 2024 unfortunately. See pic below.
I contacted GM customer service. They recommended a different part number, 84689768, that arrived and was also too small (2024 size).
I have installed the other black badges- part number 85656089. It includes 6 black badges— the 2 x AT4 badges in black for the driver and passenger doors, 2 x GMC black front quarter panel inserts, and the lift gate Yukon and AT4 badges in black. See pics below.
They told me to check back in regularly and eventually they will have a matching part number for the 2025 rear GMC emblem on the AT4.
For now it looks like … pics below.
