Good catch...I did not notice that before. The antenna looks flatter too. I wonder if anyone in the forum has one of these. The previous owner of our 2018 Tahoe put larger tires on, so I want o install the flares. Hopefully, I can get the part numbers I need to order them.
I've been pretty darn happy with my EGR OE Tahoe Fender Flares. Ours are challenging flares because the rear flares are actually 2 pieces instead of 1, due to the rear doors.
They come flat black ABS plastic, slightly textured but not much. Had mine sanded, primed and painted black to match the Tahoe.
I've removed them several times, also testing a new flare weather strip liner this winter. All-in-all: happy
