Yep, they were different. On '08s there were two different lengths. Not sure about now though. They help hide the front axle other things under the front. Ford also said it helps with fuel mileage with them being longer the higher the truck is.
The 4wd air dam is about 7 1/4". The 2wd is about 3 1/2'' I think? I can't remember, I can measure later. I've had the 2wd on since new, my 4wd valance is tucked away.
Is the plastic fascia under the front bumper shorter on the 2wd trucks than it is on the 4wd?
It is much shorter, and in my opinion way better looking. I swapped mine out over the summer. The only thing I didn't do was remove the two brackets that hang down behind it, but I plan to. It actually looks like the front end has some ground clearance now. I also like being able to see my diff and stuff, just like on my 6.0
