I installed a set of WeatherTech Mud Flaps on my 2021 GMC Sierra Denali 3500HD. Very impressed with the ease of installation and the overall appearance.
You can get these Weather Tech No Drill Mud Flaps (front and rear) for your 2020 - 2023 GMC Denali on Amazon or E-Trailer or retailer of choice. (part # 110120-120120)
