2024 F250 Tremor Valance

2024 F250 Tremor Valance. What is actually different between the 2024 250 and 350 tremor? This is my 2nd super duty but my first tremor.

The amount of wind pushing against that valence at 80 mph is considerable, and i personally think those pieces are for the valance to push against so it stays straight and stable. So i just took off the huge lower front valance panel on my 23 xlt 4×4 and ordered part# pc3z17626ca.
