No trimming, mine doesn't have the active air dam. Some do and some don't. My buddy has the active air damn on his STX and it hangs down about 2" more than mine
This is my 4th F-150 and by far my favorite. Purchased in March. Its a STX 157" wheelbase, 5.0L
Tinted Front windows
Matte Black STX decal
AutoSpring 2.5" level
Motiv Mutant 20x9 with +18 offset, just a slight poke.
285/65R20 BFG KO2's
No rub at all with this set up and still rides nice.
