My '17 sat at least 2" higher than my '25 does and I snagged it more than once on snow banks and high curbs. When the '25 came in, a new 2wd valance was one of the 1st modifications that I made. I just couldn't convince myself that cutting the 4wd valance would look as good as the 2wd version, which I picked up on eBay for a very reasonable price.

I used to buy the 2wd valance but this 2024 truck i just marked it and cut it with a razor knife. If you’re handy and strong it’s super easy. If you work in a cubicle it may pay to buy one. Or, you could use a saw i guess…

Its that way for aerodynamics and cooling. Ford does extensive wind tunnel testing and makes them this way for a reason. We may never see the actual reason for it being so big, but Ford did. Maybe to reduce the amount of drag under the truck by directing the most mass around the side? If you look closer at the bumper and headlights, there are small ducts leading to other areas of the truck, like for moving air around the tire instead of air hitting it head on.
I would say these are more likely carry ups from the F150 trucks because those have to meet CAFE and EPA standards, but the SD trucks don't so we won't see a difference removing the baffle, but the F150 would. Mine has hit quite a few things and the bottom edge is a bit scuffed. It does hang down too low, at least on the other trucks I could crawl under the front bumper, not on this one.

So, because of the truck height, they sacrifice aerodynamics and cooling on either the 2WD's or the Tremors that have the shorter chin spoiler? I guess it's a projected mix based on their sales and the gov't regs that they need to meet overall, but I don't see this making any noticeable difference in the real world. Maybe in a wind tunnel, sure, but not on the road where conditions are always variable.

You are probably right about the carry up. We all need to keep in mind that many things the manufacturers do is NOT because it's better in the real world, but because they are trying to meet CAFE standards.
