Squares did go through the wind tunnel (remember the bump on the front of the hood?) and the front spoiler was for aero. It helps clean up the airflow and push the air around the sides of the truck.
That's why the 4wd version is longer than the 2wd version (to keep them both about the same distance off the pavement).

This is not correct. Spoilers designed to throw more air into the radiator are located directly under the radiator support as opposed to under the bumper (under the bumper is too far forward for that purpose).
