I have an XLT so no skid plates, our air dams are a little different than yours. To answer your question I don't know if it is required as mine was already removed. I did have to take off the tow-hooks. My bull bar did come with extra brackets if I had a skid plate, but since I dont they were just extra parts.OFC RANGER:
When you removed the air dam did you do it to install the bull bar?
I purchased a Black Horse 3" bull bar (it matches the nerf bars and rear hitch step) and the instructions say to remove the front bolts on the skid plate and it appears the dam is in the way? Not that it affords (much) efficiency but to take it off it looks like it is fastened to every bracket, bumper, frame etc under the truck. Any suggestions?
BTW nice truck, ordered one in white and a week before it arrived I saw one in Chili pepper red and fell in love...
