Trailer Air Shields

I have seen some of them running up here with what looks like a flexible rubber skirt around the bottom foot or so of the air shield. They don't come down any further, My guess is so that if something is hit the rubber will bend and not cause damage to the air shield.

 

California... home of the 55mph speed limit? Someone there was hittin' the glass pipe during aerodynamics class. Aero mods aren't gonna do a #### thing at 55mph or below.

 

You're absolutely right, but it sure is a waste of money.

 

not nly that how do you get away with them on the back of the trailers when 53 foot trailer is the max length and those add on a few more feet

 

I was unloading in Chicago. A fedex trailer had them on there. The dock we were in had a steep decline, He slid his axles all the way forward to have less of a drop for the middle part of the trailer. I told him it wasn't going to make it, that the shields were going to get torn up hitting the ground from the decline. But super trucker over here didn't want to take advice from "The New Breed Trucker" and didn't want help guiding him back. He started rolling back, of course they scraped so he kept rolling back slowly and you can hear it scraping to the point of cracking, and what ya know the right shield cracked off. I did help him throw it in the back of his trailer. Those things are so light couldn't believe how much they cost for some fiberglass!!!!
